Suppose a weather forecast reports that the probability of snow this week is 0.20. The forecast states that if it snows this week, the probability that it snows next week is 0.29. If it does not snow this week, the probability that it snows next week is 0.15. The tree diagram depicts the possible weather event outcomes with the associated probabilities. What is the probability that it will snow next week? Provide your answer with precision 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.

What is the probability that it will snow next week? Provide your answer with precision to two decimal places.
Given ,
P( snow this week ) = 0.2
P( Not snow this week ) = 1 - 0.2 = 0.8
P( snow next week | snow this week ) = 0.29
P( snow next week | Not snow this week )= 0.15
