According to a 2017 survey conducted by the technology market research firm The Radicati Group, U.S. office workers receive an average of 121 e-mails perday (Entrepreneur magazine website). Assume the number of e-mails received per hour follows a Poisson distribution and that the average number of e-mailsreceived per hour is five.a. What is the probability of receiving no e-mails during an hour (to 4 decimals)?b. What is the probability of receiving at least three e-mails during an hour (to 4 decimals)? For this question, if calculating the probability manually make sureto carry at least 4 decimal digits in your calculations.c. What is the expected number of e-mails received during 15 minutes (to 2 decimals)?d. What is the probability that no e-mails are received during 15 minutes (to 4 decimals)?

X ~ Poi ( ) Where = 3 Poisson probability distribution is P(X) = e- * X / X!

Answered: According to a 2017 survey conducted by…

This problem involves empirical probability. The table shows the breakdown of 95 thousand single parents on active duty in the U.S. military in a certain year. All numbers are in thousands and rounded to the nearest thousand. Use the data in the table to find the probability that a randomly selected single parent in the U.S. military is in the Army.
