Question

Suppose a basketball player has made 344 out of 391 free throws. If the player makes the next 33 free throws, I will pay you q$12. Otherwise you pay me $24$

Step 2 of 2 :  

If you played this game 685times how much would you expect to win or lose? Round your answer to two decimal places. Losses must be expressed as negative values.

Answer 1

685[24(47/391)- 12(344/391)] = 685(7.67)

=-$5,255.75

you lose over $5,000

expected loss each game = -$7.67
