A local TV station employs Desmorelda, “Mistress of the Zodiac”, as its weather forecaster. She predicts a rainy day on the basis of Lunar phases. From statistical data (which is available to Desmorelda too) it is known that the probability of a rainy day during the Full Moon is 0,478, during the Third Quarter – 0,513, during the New Moon – 0,499, and during the First Quarter – 0,506. All phases last equally and the whole Lunar cycle takes 28 days. What is the probability that on a certain day Desmorelda will predict rain?
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.
