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.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230
