Question

Consider two boxes, first with 5-green & 2-pink and second with 4-green
& 3-pink balls. Two balls are selected from random box. If both balls are
pink, find the probability that they are from second box.

Answer 1

Answer:

Yes and No because

Step-by-step explanation:

As in the question we have read that in the first box there are 5 green balls and 2 pink balls and in the second box there are 4 green balls and 3 pink balls. So we are not sure that the selected 2 pink balls are from the second box.

Answer 2

Answer:

3/5

Step-by-step explanation:

let E1 is the event of choosing the box 1

E2 is the event of choosing the box 2

A is the event of drawing a pink ball

P(E1)=P(E2)=1/2

P(A/E1)=2/7

P(A/E2)=3/7
