Two fair dice are rolled 5 times. Let the random variable x represent the number of times that the sum 2 occurs. The table below describes the probability distribution. Find the value of the missing probability. x P(x) 0 0.868615786121484 1 2 0.00709074111119579 3 0.000202592603177022 4 2.89418004538603e-06 5 1.65381716879202e-08 Would it be unusual to roll a pair of dice 5 times and get no 2s?(enter YES or NO) Explain your answer.
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.
Two fair dice are rolled 5 times. Let the random variable x represent the number of times that the sum 2 occurs. The table below describes the
