Answer:
35/68
Step-by-step explanation:
The first box contains 3 orange balls and 4 black balls.
The second box contains 5 orange balls and 6 black balls
Total number of boxes = 2
Let Pr(F) be the probability that the first box is picked.
Let Pr(S) be the probability that the second ball is picked
Let O be the orange ball selected
Pr(F) = 1/2
Pr(S) = 1/2
Pr(O|S) = n(O) / n(S)
= 5/ 6+5
5/11
Pr(O|F) = n(O) / n(F)
= 3/ 4+3
= 3/7
Pr(S|O) = [Pr( O|S).P(S)] / [Pr( O|S).P(S) + Pr( O|F).P(F)]
= (5/11*1/2) / (5/11*1/2) +(3/7*1/2(
= (5/22) / (5/22 + 3/14)
= (5/22) / (136/308)
= 35/68
