At a carnival, there is a raffle with 250 tickets. One ticket will win a $260 prize, nine tickets will win a $30 prize, and the remaining tickets will win nothing. If you have a ticket, what is the expected payoff?

Respuesta :

we get that the expected payoff is $2.12

[tex]E(X)=260\cdot\frac{1}{250}+30\cdot\frac{9}{250}+0\cdot\frac{240}{250}=2.12[/tex]
