A game between two players A and B consists of 10 rounds. In each round, two fair dice are rolled together. Let X denote the sum of two dice. If X>5, A wins. The player who wins the maximum number of rounds, wins the game. What is the probability that B wins the game?

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

not sure but it may be b, as i said i'm not sure.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
