A box contains 12 red balls, 9 black balls, and 5 white balls. If you pulled four balls in a row and without return. Calculate the following: 1- The probability that all the balls are red. 2- The probability that two of them are white and two are black. 3- The probability that at least one of them is white. The probability that the balls in the first order are white, the second red, the third white, and the fourth black.

Q: 5. If a number plus 4 equals two times 6, what is the number?

A:

Q: so what is the solution

A: Given N=120 P=66% X=81 We have to calculate probability that at most 81

A: Given,

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.
