Suppose you pay $3.00 to roll a fair die with the understanding that you will get back $5.00 for rolling a 1 or a 6, nothing otherwise. what is your expected value?

. and you get 5 dollars when you roll 3 or 6 when you roll something else.

So the expected value is

06+06+56+06+06+56=106=53

.

This means loosely that if you played this game a lot you should expect to win on average about 1.66 dollars, while you payed 3 to play it. Clearly this is a great idea if you want to lose money.

it should be a and d. lmk if i'm wrong xd
