Q -Stats classhas 60 students in it. The class lasts for three hours and the students ask questions at a rate of about 3 questions per hour.

Model this situation with an appropriate binomial distribution and determine the probability of receiving more than 5 questions in a class.

My answer

P(x>=6) = 1-P(x<=5)

= 1 - binom.dist (5,60,9/60,true)

Is it correct that the probability plugged in to the formula in this case = 9/60?
