An insurance company insures 4000 people against loss of both eyes in a car accident. Based on previous data, the rates were computed on the assumption that on the average10 persons in100000 will have car accident each year that result in this type of injury. What is the probability that more than 3 of the insured will collect on their policy in a given year?

use possion distribution 
 
here probability of person to get injuery of such kind p = 10/100000
n = 4000
mean = m =  np = 4000X(10/100000) = 0.4
 
p(x) = e-m.mx / x!
 
put x = 0,1,2 
 
then add all the values and subtract it from 1 
 
that’s your answer

We can use formula of 
P(r>=n)=1-p(r
So for more than 2 persons
P(r>=2)=1-p(r
            =1-p(0)+p(1)
          since m=0.4
          So,p(r)=(e^-m*m^r)/r!
      P(r>=2)=0.007926
