When a student is randomly selected (with replacement), there is a 0.18 probability that this person is taking a math class. We want to select 4 students at random. Answer the following parts: a) Does this procedure result in a binomial distribution? (check all 4 requirement) b) Create a table for the probability distribution. c) What is the probability that exactly 3 of the students is taking a math class?

Counting Principles

In statistics, the counting principle can be said to be the concept in which the quantity of an item is determined. There can be a single item, or a group of items, or items that are related to each other. In every possible set of items, the quantity of the possible item groups or their sorting measures can be determined with counting principles.
