Then 20 balls are selected (without replacement) out of the bag at random. (a) What is the probability that all your numbers are selected? (b) What is the probability that none of your numbers is selected? (c) What is the probability that exactly...
There are balls numbered 1, 2, 3, 4, 5, 6, 7 in a box, 2 balls are drawn in succession at random without replacement, and the number on each ball is noted. What is the probability that exactly one ball has an even number? (A) 3/14 (B) 2/7 (C) 3/7 (D) 12/49 (E) 4/7
The Powerball lottery is played twice each week in 44 states, the District of Columbia, and the Virgin Islands.

(Um Poker) An urn contains 11 red balls numbered 1 through 11, 11 yellow balls numbered 1 through 11, 11 green balls numbered 1 through 11, and 11 black balls numbered 1 through 11. If 4 balls are randomly selected find the probability of getting (a) a flush (ie., all balls the same color) (b) three of a kind. (Three of a kind is 3 balls of one denomination and a fourth ball of a different denomination. e.g., 5,5,5,2) (c)...
