If the number of typopgraphical errors per page follows a Poisson distribution with mean 3, what is the probability that the total number of errors in 8 randomly selected pages is 10?
Homework Answers
X ~ Poi ( 
)
Where
= 3 per page ,
For 8 pages, 8 * 3 = 24 errors
Poisson probability distribution is
P(X) = e-
*
X / X!
So,
P(X = 10) = e-24 * 2410 / 10!
= 0.0007

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...
