Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the
probabilities.
A football player completes a pass 63.4% of the time.
Find the probability that (a) the first pass he completes is the
second pass, (b) the first pass he completes is the first or second pass, and (c) he does not complete his first two passes.
(a) P(the first pass he completes is the second pass) =
(Round to three decimal places as needed.)
(b) P(the first pass he completes is the first or second pass) =
(Round to three decimal places as needed.)
(c) P(he does not complete his first two passes)
(Round to three decimal places as needed.)
Which of the events are unusual? Select all that apply.
A. The event in part (a), P(the first pass he completes is the second pass), is unusual.
B. The event in part (b), P(the first pass he completes is the first or second pass), is unusual.
C. The event in part (C), P(he does not complete his first two passes), is unusual.
D. None of the events are unusual.
