A quiz consists of 10 multiple-choice questions, each with 6 possible answers. For someone who makes random guesses for all of the answers, find the probability of passing if the minimum passing grade is 60 %.

A:
X~Binomial(10,1/6)
P(X ≥ 6) = {{{sum((matrix(2,1,10,x))((1/6)^x)(5/6)^(10 - x), x = 6, 10)}}} = {{{highlight(0.002438)}}}
