Below are three boxes containing black and white balls. The number of each color is noted inside the box. Draw a ball from box 1 and place it in box 2. Then draw a ball from box 2 and place it in box 3. Finally draw a ball from box 3. Box 1 3 white 2 black Box 2 4 white 2 black Box 3 3 white 0 black a) What is the probability that the last ball, drawn from box 3, is white? (Type a simplified fraction.)

Step 1
Let's denote the number of white balls in each box as W1, W2, and W3, and the number of black balls as B1, B2, and B3. The probability of drawing a white ball from Box 1 is P(W1) = W1 / (W1 + B1). The probability of drawing a white ball from Box 2 is P(W2) = W2 / Show more…

Three boxes of the same appearance have the following proportions of white and black balls-Box I: 1 white and 2 black; Box II: 2 white and 1 black; Box III: 2 white and 2 black. One of the boxes is selected at random and one ball is drawn randomly from it. It turns out to be white. What is the probability that the third box is chosen?

A box contains white and black balls. When two balls are drawn without replacement, suppose the probability that both are white is 1/3. Find the smallest number of balls in the box. How small can the total number of balls be if black balls are even in number?
