A dice game involves rolling 2 dice. If you roll a sum of 2, 3, 4, 10, 11, or 12 you win $5. If you roll a 5, 6, 7, 8, or 9 you lose $5. Find the expected value for the game. Below is a table for the possible outcomes for rolling two dice.

From a glance, -1.67 is the answer.

Step-by-step explanation:

You have a higher probability of losing money than gaining it due to the distribution of probability. Aka: there are more chances to lose than win. As a result, you are expected to lose money. Only -1.67 is the only negative option, which means that we dont even need to do real math since there's already only one choice.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
