Answer:
C) The expected value is -$2000, so the detective should not take the job.
Step-by-step explanation:
The expected value is the sum of products of income and probability:
E = -10,000·1.00 + 80,000·0.10 = -10,000 +8,000 = -2,000
The detective can be expected to lose money on the job, so should not take it.

Answer:
$3.50
Step-by-step explanation:
Given:
$10 for a 6, $7 for a 5, $4 for a 4, and no payoff otherwise
P(6) = 1/6 ; p(5) = 1/6 ; p(4) = 1/6 ; p(1,2or3) = 3/6 = 1/2
P(x) ____ 1/6 _____ 1/6 _____1/6 _____1/2
x______ 10 _______ 7 _____ 4 _______ 0
Expectwd value ; E(x)
Σx*p(x) = (1/6 * 10) + (1/6 * 7) + (1/6 * 4) + (1/2 * 0)
E(x) = 3.50
