What is your expected value for a game where your probability of winning is 1/7 and your profit is four times your wager

-x(6/7) + 4x(1/7)

Step-by-step explanation:

Since there was no net amount, I substituted it with x. Since there is a 1/7 chance of winning, it is being times with 4 times the wager (x). With there being a 1/7 chance of winning there is a 6/7 chance of losing. I put -x because that is the amount you would wager (spending money). If you do find a net amount be sure to substitute it for x.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
