probability question

#1
The number of cracks in a section of interstate highway that are significant enough to require repair is assumed
to follow a Poisson distribution with a mean of two cracks per mile. What is the probability that there are no cracks that require repair in 5 miles of highway?

any help guys? :yup:

2 per observation λ=2
probability of 0 k=0

:eek:e^-10
((2^0)*(e^-2)/0!)^5 for 5 observations
