A basketball player makes approximately 74% of his free-throws. If he plays in a game in which he shoots 2free-throws, what is the probability that he will make all 2? Round your answer to two decimal places if necessary.
A quiz has 8 multiple-choice questions and each question has 3 possible responses of which exactly one is correct. Find the probability that a student answers each question incorrectly. Write the answer as a fraction or a decimal, rounded to at least 4 places if necessary.
Suppose that a box of DVDs contains 12 action movies and 5 comedies.
(a) If two DVDs are selected from the box with replacement, determine the probability that both are comedies.
(b) It probably seems more reasonable that someone would select two different DVDs from the box. That is, the first DVD would not be replaced before the second DVD is selected. In such a case, are the events of selecting comedies on the first and second picks independent events?
(c) If two DVDs are selected from the box without replacement, determine the probability that both are comedies. Write the answer as a simplified fraction.
