-$0.90
Step-by-step explanation:
There are only two possible outcomes, winning $23 (W) or losing $15 (L). Therefore:
The probability of the player making his next 3 free throws (P(W)) is:
The probability of the player NOT making his next 3 free throws (P(L)) is:
Expected value (EV) is given by the payoff of each outcome multiplied by its probability:
The expected value of the proposition is -$0.90
