10

tweets per hour. Do not round your intermediate computations. Round your final answers to four decimal places.(a) What is the probability that

6

tweets are received in a given hour?(b) What is the probability that

11

tweets are received in1.5

hours?(c) What is the probability that fewer than

3

tweets are received in one-fourth hour?
