295. Two six-sided dice are rolled. Find the probability that the first die is not a 5, given that the second die is not a 2.

 (a) 2/3 (b) 29/36 (c) 25/36 (d) 5/6

296. Two six-sided dice are rolled. But this time, the dice aren't fair: For each die, a 1 is twice as likely to be rolled as a 2, a 2 is twice as likely to be rolled as a 3, ..., and a 5 is twice as likely to be rolled as a 6 (in other words, each number is twice as likely as the number that follows it). So what is the probability of rolling a sum of 7?

 (a) 64/1023 (b) 64/1223 (c) 64/1323 (d) 64/1123

297. There is a carnival game that requires you to roll two standard 6-sided dice. If the sum of the dice rolls is a prime number, then you win. What is the probability of winning?

 (a) 5/12 (b) 17/36 (c) 4/9 (d) 1/2

298. There is a standard 52-card deck. If you draw three cards randomly, what is the probability that all three cards are spades?

 (a) 23 out of 1,988 (b) 39 out of 140,608 (c) 11 out of 850 (d) 1 out of 64

299. A casino game costs \$5 to play where you roll two dice. If the sum of the dice rolls is 7, you win \$21. If the sum of the dice rolls is not 7, then you lose and get nothing. If you keep playing and stop when you win, what are the odds you will have made money?

 (a) 3750/7776 (b) 4651/7776 (c) 3125/7776 (d) 4105/7776
