Problem 1E

Let X ~ Poisson(4). Find

a. P(X = 1)

b. P(X = 0)

c. P(X<2)

d. P(X > 1)

e. μX

f. σX

Step-by-Step Solution:

Solution

Step 1 of 7

Here we have to find the poisson probabilities

The pmf of Poisson distribution is p(x)= ,x=0,1,2,............

Here X poisson( )

Given X poisson(4)

So =4
