Suppose that after completing this program at Ryerson you decide to sit the Canadian Institute of Public Health Inspectors (CIPHI) certification exam. If the oral exam has a 65% pass rate on the first attempt, a 75% pass rate on the second attempt, and an 80% pass rate on the third attempt, complete the probability tree diagram below to determine the probability of passing the exam in at most three attempts. Let S be a pass and F be a failure.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
