Answer 1

Answer #1

Answer

Option 3

the formula is: (note: the two events are mutually exhaustive and exclusive so the sum of probability of both is equal to 1)

E(2) = X* P(2) P(state 1) =1- P(state 2) P(state 1) = a P(state b) = 1-a 87.5 = 100 * a + 50 * (1 – a) = 100a + 50 – 50a = 50

the probability of state a=0.75
