Question

A basket contains 15 pieces of fruit: 7 apples, 5 oranges, and 3 bananas. Jonas takes a piece of fruit at random from the basket, and then Beth takes a piece at random. What is the probability that Jonas will get an orange and Beth will get an apple

Answer 1

does Jonas return it or no ?

Answer 2

5/15 * 7/14 =1/6

Answer 3

Jonas's probability is 5/30 = 1/6.

Answer 4

If he returns the orange, then Beth's probability is 7/30. But if he doesn't return it, then her probability is 7/29.

Answer 5

it doesnt say if they return them

Answer 6

yea, i agree with@Jas9420

Answer 7

Well, then I guess we have to assume that he doesn't return the orange that he had taken.

Answer 8

how did you get 1/6

Answer 9

Using the Probability Formula which is P(A) = Number of ways an event can occur/ The total number of possible outcomes.

Answer 10

how do you use P(A)

Answer 11

The number of ways an event can occur in Jonas' case is 5 because that is the number of apples that are there. And the total number of possible outcomes would be the sum of all the fruits which is 15+7+5+3.

Answer 12

P(A) is nothing but the probability.

Answer 13

so the number of how much is there al ltogether and the muber of hw many of the single one is there

Answer 14

Sort of.
