There are ten small towns in the central part of the state.  The weatherman for the TV channel that covers this part of the state says that the chance of rain today is 70%.  Let X denote the number of towns that get rain today.   Which of the following is correct? Group of answer choices   (  ) X is a binomial random variable with 10 trials, and chance of success 0.70 on each trial.   (  ) X is not a binomial random variable, because the trials are not independent of one another.   (  ) X is not a binomial random variable, because it is not true that each trial has exactly two outcomes.   (  ) X is not a binomial random variable, because there is not a fixed number of trials.   (  )X is not a binomial random variable, because the chance of success is not the same for all trials.

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.
