Suppose that for married couples to vote in an election, the probability that a husband will vote is 0.7, the probability a wife will vote is 0.5, and the probability a wife votes given her husband votes is 0.6. Find the probability that for a randomly selected couple, (a) Both will vote (b) Only one of them will vote.
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.
