1. (10) Initech does part of its business via Internet. However, because of the high traffic, the
server that carries the company's website often crashes. The probability distribution of the number of server crashes per week, X, is given below:
x
0 1 2 3
f (x) 0.55 0.25 0.15 0.05
x f (x) 0 0.25 0.30 0.15
x 2 f (x) 0 0.25 0.60 0.45
0.70
1.30
If the server does not crash, Initech's profit weekly from the website is $50,000. However, each time the server crashes, Initech looses $20,000. Therefore, Initech's weekly profit from the website (in thousands of $) is Y = 50 20 X. Find Initech's average weekly profit from the website and its standard deviation.
E( X ) =
x f ( x)
all x
= 0.70.
Var ( X ) = E ( X 2 ) - [ E ( X ) ]
2
=
x 2 f ( x) - [ E ( X ) ] 2
all x
= 1.30 - ( 0.70 )

= 0.81.
SD ( X ) =
0.81 = 0.90.
E ( Y ) = 50 20 E ( X ) = 50 20 0.70 = 36. SD ( Y ) = | 20 | SD ( X ) = 20 0.90 = 18.
