sammy is playing a board game. he rolls two number cubes, each numbered 1-6. if he rolls a sum of 3 he wins s60 dollars, otherwise he loses

$5 dollars. how much does sammy expect to win or lose on average per roll.

Sammy is expected to lose $1.39 on average per roll

Step-by-step explanation:

Since Sammy is rolling two six-sided cubes, the number of possible outcomes is given by:

6 x 6 =36

Out of those 36 outcomes, only two would result in a sum of 3, rolling a 1 and 2 or a 2 and a 1. Therefore, the probability of winning (P(W)) and the probability of losing (P(L)) are:

The expected value is defined as the sum of the product of the likelihood of each event by its payout:

Sammy is expected to lose $1.39 on average per roll.

x/3-10=8

x/3=18

x=48

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
