Football player Ben Roethlesberger completes a pass 64.1% 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.

Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine whether the events are unusual. If convenient, use a table or technology to find the probabilities.
