Suppose the number of accidents occurring on a highway in each day follows a Poisson random variable with parameter 3 . Then, what is the probability that no accidents occur today?
Options
- A1 e 3
- B- 1 e 3
- C1 e 9
- D- 1 e 9
Correct answer
A. 1 e 3
Step-by-step solution
Given: λ = 3 P ( X = x ) = λ x e - λ x ! Probability that no accidents occur today = P X = 0 = 3 0 e - 3 0 ! = 1 e 3 .
