1. What is the expected value and standard deviation for the number of defective automobiles that the auto dealer will receive?

2. What is the probability (P) that the auto dealer will receive at least one defective automobile?

 

a. Standard deviation
2.10
O b. Expected value = 7
c. P= 0.00014
O d. Standard deviation = 1.73
e. P= 0.149
f.
P = 0.028
g. standard deviation = 1.45
O h. P = 0.12
O i. Expected value = 3
O j. P= 0.972
O k. Expected value = 2.1
