A basketball player has made 75 out of 100 free throws durin

A basketball player has made 75 out of 100 free throws during the season. She is about to shoot her next free throw. For $7 you can buy a betting ticket that \"pays off\" $10 if she makes it. Would you buy a ticket? Would you buy more than one?

Solution

probability for her to make a throw

= 75/100 = 3/4

if she makes = +10(3/4)

if she doesn\'t = -7(1/4)

net is 10(3/4) - 7(1/4) = 23/4

so yes i will buy a ticket
