In Vancouver, British Columbia, the probability of rain during a winter day is 0.58, for a spring day it is 0.38, for a summer day it is 0.25 and for a fall day it is 0.53. Each of the four seasons lasts one quarter of the year. If you were told that on a particular day it was raining in Vancouver, what would be the probability that this day would be a winter day? The answer should be a number between 0 and 1. How to know which probability formula to use?
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.

How to know which probability formula to use?
Let E1 = Event that the selected day is a winter day
E2 = Event that the selected day is a spring day
E3 = Event that the selected day is a summer day
E4 = Event that the selected day is a fall day
R = Event that there is a rain on the selected day
