The given problem has been rewritten, to make it more readable

Two balls are drawn in succession out of a box containing 3Red and 5 whiteballs. Find the probability that at least 1 ball was Red, given that the first ball was {A}replaced before second draw, {B} not replaced before second draw.

B Now, if the ball drawn first is not replaced, the probability of drawing at least one red ball in both draws would be as under:

Ans A =39/64. Ans B= 9/14

Suppose that there is a white urn containing two white balls and three red balls and there is a red urn containing two white balls and four red balls. An experiment consists of selecting at random a ball from the white urn and then (without replacing the first ball) selecting at random a ball from the urn having the color of the first ball. Find the probability that the second ball is red.

Two balls are chosen randomly from a box containing 8 white, 4 red, and 2 green balls to see if you will win any money. Suppose that you win $2 for each red ball selected, you lose $1 for each blue ball selected, and you get nothing for each green ball selected. What is the probability that you will not lose any money?
