Supposean individual plays a gambling game where it is possible to lose $1.00, break even, win $4.00, or win $18.00 each time she plays. The following table provides the probability distribution for each outcome Outcome -$1 $0 $4 $18 Probability 0.3 0.4 0.2 0.1 Find the mean and the variance of the outcome
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.
Supposean individual plays a gambling game where it is possible to lose $1.00, break even, win $4.00, or win $18.00 each time she plays. The following table provides the probability distribution for each outcome
| Outcome | -$1 | $0 | $4 | $18 |
| Probability | 0.3 | 0.4 | 0.2 | 0.1 |
Find the mean and the variance of the outcome.
