According to a recent poll taken in August by Pew Research, 83% of men said that they regularly wear a mask when in stores or other businesses and 87% of women said the same. Suppose in a large city, 55% of the population is women and 45% is men. The probability that we randomly choose a resident that does not regularly wear a mask given that the resident is a male is to be determined. Which of the following would be the most appropriate method to use to determine this conditional probability? Use a Venn Diagram with one circle being the probability that a man does not wear a mask and the other circle the probability that a woman does not wear a mask. Put the probabilities in a contingency table with the rows being the probability of male/female and the columns being the probability of mask/no mask. Use a Venn Diagram with one circle being the probability that a man does not wear a mask and the other circle the probability that a man does wear a mask. Since wearing a mask is independent of gender, multiply the probabilities. Use a Tree Diagram with Male/Female as your first branch and then mask/no mask as YOur next branches

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.
