The probability function for the number of insurance policies John will sell to a customer is given by
f(x)
= 0.5
for X =
6.
0, 1, or 2.
(a) Is this a valid probability function? Explain your answer.
Yes, f(x) 2 0 and Ef(x) + 1
Yes, f(x) > 0 and Ef(x)
= 1
No, f(x) > 0 and Ef(x) # 1
No, f(x) > 0 and Ef(x)
= 1
