The increased number of small commuter planes in major airports has heightened concern over air safety. An eastern airport has recorded a monthly average of nine near misses on landings and takeoffs in the past 5 years. (Round your answers to three decimal places.)

(a) Find the probability that during a given month there are no near misses on landings and takeoffs at the airport . 

(b) Find the probability that during a given month there are three near misses.

(c) Find the probability that there are at least three near misses during a particular month.

Find the following binomial probabilities. Show all your work. Round to 4 decimal places. Find the probability that exactly 6 of 25 are successes. Find the probability that at least 10 of 25 are successes. Find the probability that at most 5 of 25 are successes. Find the probability that there are between 3 and 7 successes, inclusive.

Probability of Hitting a Target The probability that an archer hits the target is p=0.9, so the probability that he misses the target is q =0.1. It is know that in this situation the probability that the archer hits the target exactly r times in n attempts is given by the term containing in the binomial expansion of . Find the probability that the archer hits the target exactly three times in five attempts.

Find the probability. A 12-sided die, numbered 1 to 12, is rolled. Find the probability that the roll results in an odd number or a number less than 4.
