You host a house party with 4 guests attending. Every guest gets a chance to win a gift by spinning a wheel with 1/3 of a chance of stopping at the winning spot. If you prepare 2 gifts to give away, what is the probability of you being embarrassed for running short of gifts (i.e, there are more winners than the number of gifts). Round your answer to two decimal places (for example: 0.12)

Multiple-choice questions each have 6 possible answers, one of which is correct. Assume that you guess the answers to 5 such questions. Use the multiplication rule to find the probability that the first four guesses are wrong and the fifth is correct. That is, find P(WWWWC), where C denotes a correct answer and W denotes a wrong answer. (round answer to 4 decimal places) P(WWWWC) What is the probability of getting exactly one correct answer when 5 guesses are made? (round answer to 4 decimal places) P(exactly one correct answer) = %3D
