Question

1. For a discrete random variable that is Poison distributed with = 9.6, determine the following:

a. P(x = 7) =  

b. P(x = 9) =  

c. P(x 12) =  

d. P(x 10) =

2. 0.5% of the checks received by an oil company is returned due to insufficient funds. Yesterday 650 checks were received in the mail. Let x equals the number of these checks which will be returned due to insufficient funds.

Use the Poisson distribution to compute the binomial probability that one or more checks are returned.

P(x [greater than or equal to] 1) =

3. 1% of the checks received by an oil company is returned due to insufficient funds. Yesterday 450 checks were received in the mail. Let x equals the number of these checks which will be returned due to insufficient funds.

Use the Poisson distribution to compute the binomial probability that less than three checks are returned.

P(x < 3) =
