Text message users receive or send an average of 41.5 text messages per day.

a) How many text messages does a text message user receive or send per hour?

b) What is the probability that a text message user receives or sends two messages per hour?

c) What is the probability that a text message user receives or sends more than two messages per hour?

X= 41.5/24

1.7292

XP(1.7292)

P(x=2)=poissonpdf(1.7292,2)0.2653

P(x>2)=1-P(x2)=1-poissoncdf(1.7292,2)1-0.7495=0.2505

PLEASE explain how to compute the poissonpdf and poissoncdf in the above question. How it end up in the final answers? Thanks
