I just finished my math final. There's 55 questions I had to do but I didn't finish the last 7 problems. The final is worth 200 points. I have a 75.47% in the class, will I pass it? Depending what I get right and what I get wrong on it too...(Not a problem just need someone to do the calculations for me)

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
