XP(X)

--------------------------------------------------------------

5|0.27

6|0.23

7|0.23

8|0.17

9|0.10

10|0.00

Compute the expected value.

SELECT ALL APPLICABLE CHOICES

A)μ=2.7

B)μ=6.6

C)μ=3.4

D) None of These

Answer 1

Solution

Answer : B) 6.6

$\mathbf{X}$	PX)	X*P(X)
5	0.27	1.35
6	0.23	1.38
7	0.23	1.61
8	0.17	1.36
9	0.10	0.90
10	0.00	0.00
	ΣΡ (X) = 1	X*P(X) = 6.6

Expected value = X*P(X) = 6.6
