Suppose a basketball player has made 217 out of 302 free throws. If the player makes the next 3 free throws, I will pay you $23. Otherwise you pay me $15. Step 1 of 2 : Find the expected value of the proposition. Round your answer to two decimal places. Losses must be expressed as negative values.
1 answer:
Answer:
-$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
