Question

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?

Answer 1

Answer:

0.008

Step-by-step explanation:

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
