Question

A bag contains 5 blue marbles and 8 orange marbles. Polly draws a marble from the bag and then replaces it back into the bag. Perry then draws a marble from the bag. What is the probability that both Polly and Perry draw an orange marble from the bag?

Which expression will find the answer?

A) 8/13 x 7/12

B) 13/8 x 13/8

C) 13/8 x 12/7

D) 8/13 x 8/13

Answer 1

d is the answer ooooo

Answer 2

Given there are 5 blue marbles and 8 orange marbles.

Total number of marbles in the bag =5+8=13.

Probability of Polly drawing an orange marble =
`(8)/(13)`

As the marbles are replaced .

Probability of Perry drawing an orange marble =
`(8)/(13)`

The probability that both Polly and Perry draw an orange marble from the bag =
`(8)/(13) x (8)/(13 )`

Option D is the right answer.
