A bag contains 7 green and 5 black balls. Three balls are drawn one after the other. The probability of all three balls being green, if the balls drawn are not replaced will be:

Assume that you randomly pick one of the bowls: X, Y, or Z. You then randomly draw one ball out of the selected bowl and note its color. The bowls contain the following colored balls: Bowl X: 2 red, 4 white, and 2 blue. Bowl Y: 2 red, 2 white, and 1 blue. Bowl Z: 2 red, 2 white, and 2 blue. (2) If the ball is either blue or white, what is the probability that it was drawn from bowl Y?

A die is being thrown twice. Find the probability of getting 5 and 1 in each respective throw.

An urn contains eight white balls and two red balls. A second urn contains two white balls and a red balls. An urn selected and a balls randomly drawn from selected urn. The probability of selecting the first urn is. 65. If the ball is white find the probability that the second urn was selected.
