10. Emergency Savings The table shows the results of a survey in which 141 male and 139 female workers ages 25 to 64 were asked if they had at least one month’s income set aside for emergencies. Male Female Less than one month’s income M is 62 F is 81 One month’s income of more M is 79 F is 58 a) Find the probability that a randomly selected worker has one month’s income or more set aside for emergencies, given that the worker is female. b) Find the probability that a randomly selected worker is female, given that the worker has less than one month’s income set aside for emergencies.
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.
