Answer:
Step-by-step explanation:
Given that the possible values of X, the number of components in a system submitted for repair that must be replaced are 1,2,3, and 4 with corresponding probabilities 0.15, 0.35, 0.35, and 0.15 respectively.
X 1 2 3 4
p 0.15 0.35 0.35 0.15 1
x*p 0.15 0.70 1.05 0.60 2.50
a)E(x) = 2.50
By linearity property
E(5-x) = 5-E(x) = 2.50
b) If fees it 75 then charges would be
Else repair charges =
