On each of three consecutive days the National Weather Service announces that there is an equal chance of rain or no rain. Assuming that the National Weather Service is correct, answer the following questions to find the probability that it rains one of the three days. (Hint: Represent the outcome that it rains on day 1 and doesn’t rain on days 2 and 3 as RNN. A tree diagram can help you find the sample space.) How many outcomes are in the sample space? How many outcomes are in the event where it rains one of the three days? What is the probability that it rains on one of the three days?
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.
