Question 875139: What are the chances that a student can get a grade of a C, B or A when they guess on a multiple choice test? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! Let's say 4 choices: p(correct) = .25 , n = 100
P(x ≥ 70) = 1 - binomcdf(100, .25, 69)= 1 - 1 = 0, Basically 0% chance of a C
Obviously same holds for B or A
