Question

Assume that the number of network errors experienced in a day on a local area network (LAN) is distributed as a Poisson random variable. The mean number of network errors experienced in a day is 2.6. Complete parts (a) through (d) below. b. What is the probability that in any given day exactly one network error will occur? The probability that exactly one network error will occur is 0.1931. (Round to four decimal places as needed.) c. VWhat is the probability that in any given day two or more network errors will occur? The probability that two or more network errors will occur is (Round to four decimal places as needed.)

Explanation / Answer

Ans:

mean=2.6 per day

b)P(x=1)=e-2.6*(2.61/1!)=0.1931

c)P(x>=2)=1-P(x=0)-P(x=1)=1-e-2.6-0.1931=1-0.0743-0.1931=0.7326
