Exactly 20% of the students in a school wear glasses. sixty-five students are randomly selected to determine the probability that exactly 10 students wear glasses. should a binomial probability density function or a cumulative distribution function be used? explain.
a binomial cumulative distribution function should be used because the question asks for determining the probability that exactly 10 students wear glasses.
a binomial probability density function should be used because the question asks for determining the probability that exactly 10 students wear glasses.
a binomial cumulative distribution function should be used because the question states exactly 20% of students wear glasses.
a binomial probability density function should be used because the question states exactly 20% of the students wear glasses.
a binomial probability would not be used because the events are not independent of each other.
