An urn contains 1 white, 2 black, 3 red, and 4 green balls. If 6 balls are selected randomly (without replacement) and X represents the number of selections that are either red or green, find: (a) the probability mass function for X. (b) the expected value of X (calculate this value directly by using the probability mass function from part a).

Suppose that an urn contains 8 red balls and 4 white balls. We draw 2 balls from the urn without replacement. Now suppose that the balls have different weights, with each red ball having weight r and each white ball having weight w. Suppose that the probability that a given ball in the urn is the next one selected is its weight divided by the sum of the weights of all balls currently in the urn. Now what is the...

One urn contains 10 red balls and 10 white balls, a second urn contains 8 red balls and 4 white balls, and a third urn contains 5 red balls and 10 white balls. An urn is selected at random, and a ball is chosen from the urn. If the chosen ball is white, what is the probability that it came from the third urn? Justify your answer.

In an urn, there are 20 balls of four colors: red, black, yellow and blue. For each color, there are 5 balls and they are numbered from 1 to 5. 1) If one ball is randomly drawn from the urn, what is the probability that the randomly selected ball is red or blue? 2) If one ball is randomly drawn from the urn, what is the probability that the randomly selected ball is numbered 1 or blue?

We have two urns: Urn A contains 6 red balls and 4 white balls, Urn B contains 4 red balls and 8 white balls. A die is rolled, if a number less than 3 appears; we go to box A; if the result is 3 or more, we go to ballot box B. Then we extract a ball. It is requested: to. Probability that the ball is red and ballot box B. b. Probability that the ball is white.
