Cabs pass your workplace according

Cabs pass your workplace according to a Poisson process with a mean of five cabs per hour.
(a) Determine the mean and standard deviation of the number
of cabs per 10-hour day.
(b) Approximate the probability that more than 65 cabs pass
within a 10-hour day.
(c) Approximate the probability that between 50 and 65 cabs
pass in a 10-hour day.
(d) Determine the mean hourly rate so that the probability
is approximately 0.95 that 100 or more cabs pass in a
10-hour data.
