Jill and Zoe have lunch together. They flip a coin to decide who pays for lunch and then flip a coin again to decide who pays the tip. (a) List the simple events in the sample space. Define a possible outcome to be who pays for lunch and who pays the tip, in order—for example, (J, J). (Enter your answers as a comma-separated list. Use J for Jill and L for Zoe.)     (b) Are the simple events equally likely? If not, why not? No, the person who pays the bill is less likely to have to pay the tip as well.No, the person who pays the bill is more likely to have to pay the tip as well.     No, Zoe is more likely than Jill to have to pay for both.No, Jill is more likely than Zoe to have to pay for both.Yes, the simple events are equally likely. (c) What is the probability that Zoe will have to pay for lunch and leave the tip? (Enter your probability as a fraction.)

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.
