A container contains 30 tokens
A container contains 30 green tokens, 15 blue tokens, and 3 red tokens. Two tokens are randomly selected without replacement. Compute P(F|E).
E−you select a blue token first
F−the second token is blue
Homework Answers
Total token = 30 + 15 + 3 = 48
15/48 * 15/48 = 0.097656
= 9.7656%

1. Suppose that a friend gives us the chance to participate in a game. The game is as follows. There is a bucket containing 6 green tokens and 18 red tokens. We are to blindly reach into the bucket and randomly choose one token. Keeping this token (i.e. the chosen token is not returned to the bucket) we are to once again reach in blindly and randomly retrieve another token. If the first token we have chosen is green and...

19. An urn contains 30 balls identical in every respect except color. There are 15 red balls, 7 green balls, and 8 blue balls. You draw two balls from the urn (without replacing the first ball before drawing the second). Find the probability that the first ball is green and the second is blue. Express your answer as a decimal.

Question 3 6 pts A hat contains four red cards numbered 1 through 4; five blue cards numbered 1 through 5; and two green cards numbered 1 and 2, respectively. Find the following probabilities (with replacement). Give your answers as fractions. a. P(Blue) = b. With one draw, P(Blue and Even) = c. With one draw, P(Blue or Even) = d. With one draw, P(Red Even) = e. With one draw, P(Even/Red) = f. With two draws, P(first card Green...
