Q2. One organization argues that the sonar system using in the Navy constitutes a substantial risk to marine life, such as causing extraordinary numbers of stranded or beached whales. There are the following statements. a. On any given day, the probability of a mass stranding of whales in this area is 0.01. b. The probability of a military exercise on any given day is 0.001. c. If there is a military exercise, the probability of a mass stranding is 0.17. Define events and write a probability statement for each fact above. On a randomly selected day, what is the probability of a mass stranding of whales and a military exercise? Are the events mass stranding and military exercise independent? Justify your answer.
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.
