Jason rolls a fair number cube labeled 1 through 6 , and then he flips a coin. What is the probability that he rolls a 3 and flips a head?

The probability of rolling a 3 is 1/6, and the probability of flipping a head is 1/2. Since the roll and flip are independent, multiply the probabilities: 1/6 × 1/2 = 1/12. So the probability is 1 over 12, choice C.
