plz help me on probability questions.

either give me answers for each or tell me the concept to do each1) a canister contains 20 pieces of candy: 5 strawberry flavored, 9 watermelon flavored, 6 mint flavored. Two are selected at random. Find probability of eacha) 2 strawberry b) 1 strawberry, 1 mint2) Tom’s bank contains 7 pennies, 4…

1) a) the prob of picking strawberry on first try is 5/20, second is 4/19. Multiply them and you get 2/38b)prob of picking strawberry, then mint is (5/20)(6/19)prob of picking mint, then strawberry is (6/20)(5/19), add them together and you get = (6/38)2)a) same as previous (7/16)(6/15)(5/14) = .0625b) (5/16)(4/15)(3/14) times 3 (3 different orders) = .01785c) (7/16)(4/15)(5/14) times 6 (6 different orders) = .04166663)because it says “in that order” you don’t have to worry about the other possible orders, just multiply the probabilities like above.4)The way I would do this problem is forget about the dictionary, then find how many ways the five books can be ordered, then multiply by two because for each possiblity the dictionary can be either first or last.so 5*4*3*2*1 = 5!then *2 = 2*5! = 2405) Multiply the number of possibilities for each digit.26 letters, 10 one digit numbers, 9 if cant be 026*26*10*10*9 =608400

the questions are below.

1. Which product would represent the total number of license plate possibilities given that a license plate is three letters followed by three digits?a. 36 x 36 x 36 x 9 x 9 x 9b. 26 x 26 x 26 x 9 x 9 x 9c. 24 x 24 x 24 x 10 x 10 x 10d. 26 x 26 x 26 x 10 x 10 x 102. When creating your fall…

yes, do your homework like this!1♦ d; there are 26 letters and 10 digits and no more restrictions!2♦ d; 120=5*3*4*2;4♦ b; 21= 7*6/2;5♦ c; 210= 7*6*5;

morning math questions below.

1. How many combinations can be formed from the letters “F L O R I D A” taking two at a time?2. Three marbles are to be drawn successively from a bag that contains 4 white marbles, 2 red marbles, and 3 green marbles. (Note that the marbles are not replaced after they are drawn from the bag.) What is…

1) the problem explicitly states that its a combination and not a permutation. Also, since the letters of FLORIDA are distinct, then we simply use: number of letters in FLORIDA C 2 which is the same as: 7C2 = 21. thus, there are 21 combinations2) since the marbles are not replaced, then the number of marbles in the bag decreases by 1. thus, we simply add the number of marlbles first=4+2+3 = 9. If the person chooses white, the probability would be 4/9. when the person chooses red, the probability would now be 2/8 and lastly, when green marbles are chosen, the probability would now be 3/7. Since the events are independent, we simply multiply. Multiplying, probability becomes 1/21.3)It is simply an application of the fundamental counting principle. So, since there are 5 choices for english, 3 for math, 4 for science, 2 for history, then we simply multiply them or: 5X3X4X2 = 120 ways.4)first step is to pick 3 books from the 7 books. Note that we choose 3 books and order doesnt matter. So, the number of ways is denoted by: 7C3=35 ways. However, we need to arrange the 3 we’ve chosen on the shelf which is a permuatation problem thus, we have 35x 3! = 35X6 = 210 ways :D:D:D i hope youd understand

How many ways can you arrange the books on a shelf if the books are grouped by author.

You have 7 different books written by Tom Clancy, 4 different books written by Louis L’Amour, and 5 different books by Isaac Asimov. How many ways can you arrange the books on a shelf if the books are grouped by author?

I’ve done this here at home.Arranged alphabetically by titleby hardback then paperback or vice-versa, which is likeby size, taller to shorter, or v-versa.By color of jacket or spine. I don’t like the look of all one color together, and I think it makes items harder to distinguish.Some of mine have gold lettering on spine, and they get special display, lying flat in a stack.By date of publication; with longest-ago author coming first or v-v Some of mine flow upward in reverse chronology, it just seemed to happen.Favorites could be placed where easiest to reach.If you were really pressed for shelf space, one row could be behind the other; some of my videos are.Can arrange authors by alphabetor by subject: maybe “Western” comes after “Adventure” in your mind.They’re all men. In several cases I have women authors of about same time grouped together.By rank in the world outside books: Clancy had military rank, I think – the books are upstairs. Asimov had a Ph.D. Lamour, no title that I’m aware of.Your favorite author could come first. Maybe you love and/or live in the South West, so that might be Lamour.Individual books ;might have personal significance for you. Those might be first within each author’s group.You could use one method for one author, another for another — or not.Or you could mix all of this up, which seems not like “arranging” at all.This si not a math answer, but I would arrange them in the way that most suits you!

  1. 1. circular field has a radius of 55 m a. find the circumference of the field. C = 2π x radius = 2 x 3.14 x 55 = 345.4 m b. find its area A = πr² = 3.14 (55)² =9498.5 m² 2. a disk has a diameter of 8 cm . a. what is its circumference Substitute the diameter value and get the answer C = π x diameter b. what is its area Diameter = 8 cm radius = 4 cm Then substitute it in the formula below and get the answer A = πr² 3. when juliette swims across her circular pool and back, she travel a total distance of 16. she swims through the centre of the pool both ways. find the surface area of the swimming pool. Answer Since she always crosses the centre, thus, she has traveled on the diameter of the pool Since she traveled to and fro, distance = 16 Thus, diameter = 8 Radius = 4 Apply A = πr² and get the answer 4. lars walks a distance of 120 m. halfway around a circular field. how much less would he walk if he walked straight across the diameter Since he walked around a circular field, which means he covered the circumference. As it was halfway around the field, so distance = 1/2Circumference C = π x diameter 1/2 x π x diameter = 120 Multiplying both sides by 2 π x diameter = 240 Dividing both sides by π diameter = 240/π = 76.43 Difference in distance = 120 – 76.43 = 43.57 m 5.estimate the length of the missing side in each traingle. then, use a calculator to find the approx. length , to the nearest tenth a. 5 cm 8cm b. 26cm 16cm Is the triangle a right angled triangle? Otherwise with no information about the nature of triangle, we cannot find the third side. 7. Renata swims diagonally across a square pool. each side side of the pool is 8 m long. how amny times will she need to go diagonally across the pool to complete a distance of 100 m round your answer to the nearest whole number. Answer Diagonal divides the square into two equal right triangles with the diagonal as the hypotenuse. So base = perpendicular = 8 m hypotenuse = diagonal (Hyp)² = (base)² + (perp)² (Hyp)² = (8)² + (8)² (Hyp)² = 64 + 64 (Hyp)² = 128 hyp = √128 hyp = 11.3 m Diagonal length = 11.3 m Number of rounds = 100 / 11.3 = 8.85 Number of rounds = 9

  2. 1.) if the candies are pulled out at once than the probability is 5/20 * 4/19 = 20/380 = 1/19, 5/20 * 6/19 = 30/380 = 3/38

  3. If each and each senior’s call is put in thrice then there are 3 hundred seniors names interior the lottery and in addition there are 3 hundred juniors names and 2 hundred sophomores names so in finished there are 800 interior the lottery of which 3 hundred are seniors subsequently the possibility that a senior’s call would be picked is 3 hundred/800=3/8

  5. Put the authors in Alphabetical Order Put them in the order you like them Put them in the order of which you intend to read them (or the order you read them in)
