This week Next week Suppose a weather report indicates that the probability of rain this week is 0.20. According to the report, if it rains this week, then the probability of rain next week is 0.33. If it does not rain this week, then the probability of rain next week is 0.17. The tree diagram models this weather report. Rain 0,33 Rain 0,20 Determine the probability that it will not rain for the next two weeks. Express 0.67 No rain your answer as a decimal precise to two decimal places.

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.
