Answer:
0.195
0.191
Step-by-step explanation:
Given that :
μ = 4
Using poisson :
P(x) = (e^-μ * μ^x) ÷ x!
P(x = 3) = (e^-4 * 4^3) / 3!
= (0.0183156 * 64) / 6
= 0.1953664
= 0.195
b. What is the probability that he will sell at most 5 policies in two weeks period?
Mean per week = 4
Mean in two weeks = 4 * 2 = 8
P(x ≤ 5) = p(5) + p(4) +... + p(0)
Using the poisson distribution calculator :
P(x ≤ 5) = 0.19124
= 0.191
