Answer:
Option C: E(X) = 1.65
Step-by-step explanation:
Expected value of X, E(X) = ∑XP(X)
∑ = Summation
X = number of hours
P(X) = probability of a certain number of hours
E(X) = (0*P(X=0)) + (1*P(X=1)) + (2*P(X=2)) + (3*P(X=3)) + (4*P(X=4))
E(X) = (0*0.2) + (1*0.2) + (2*0.4) + (3*0.15) + (4*0.05)
E(X) = 0 + 0.2 + 0.8 + 0.45 + 0.20 = 1.65
E(X) = 1.65 - Option C
