Abox has 2 blue and 9 green jelly beans. a bag has 3 blue and 9 green jelly beans. a jelly bean is selected at random from the box and placed in the bag. then a jelly bean is selected at random from the bag. if a green jelly bean is selected from the bag, what is the probability that the transferred jelly bean was green? (round your answer to three decimal places.)

0.833

Step-by-step explanation:

Given that a jelly bean is seclted at random from the box and placed in the bag. This one can be either blue or green.

A1 - If blue is selected and put in the bag, then bag would have 4 blue and 9 green now.

A2 -If green is selected and put in the bag, then bag would have 3 blue and 10 green now.

Let B be the event that the jelly bean selected from the bag was green.

Required probability = P(A2/B) =

=0.833

you just switch the numbers basically so it would be 3/17
