Probability

Question

The number of accidents on a particular road averages 2.1 per day. Assuming that a Poisson distribution is appropriate, find the probability that 4 accidents will occur on a given day

Answer 1

.099

 

Use the poisson formula with

L = 2.1 and k= 4

 

(L^k*e^-L)/k!

 

(2.1^4*e^2.1)/4!
