The number of errors in a sequence follows a Poisson distribution. The average number of errors in 50 members of the sequence is 1.2. (a) What is the probability of exactly three flaws in 150 members of the sequence? (b) What is the probability of exactly one flaw in the first 50 members of the sequence and exactly one flaw in the second 50 members of the sequence? Since this is a Poisson distribution the two parts of the sequences...

The number of automobiles entering a tunnel per 2-minute period follows a Poisson distribution. The mean number of automobiles entering a tunnel per 2-minute period is four. (A) Find the probability that the number of automobiles entering the tunnel during a 2minute period exceeds one. (B) Assume that the tunnel is observed during four 2-minute intervals, thus giving 4 independent observations, X1, X2, X3, X4, on a Poisson random variable. Find the probability that the number of automobiles entering the...
