A vase U1 contains 2 white balls, a vase U2 contains 2 red balls, a vase U3 contains 2 white balls and 2 red balls and vase U4 contains 3 white balls and 1 red ball. The probability of choosing vase U1, U2, U3, and U4 are respectively 1/2, 1/4, 1/8 and 1/8. A vase is chosen and we retrieve the ball inside. Determine
a) The probability that the retrieved ball is white
b) Knowing the retrieved ball is white what is the probability that the ball was retrieved from vase U3.
