Question

Suppose it costs ​$48 to roll a pair of dice. You get paid​ $7 times the sum of the numbers that appear on the dice. Is it a fair​ game?

Answer 1

9514 1404 393

Answer:

no

Explanation:

The expected value of the sum of a pair of dice is 7, so the game's expected value is -$48 +$7×7 = $1. This is not zero, so the game is not fair.
