A test was given to a group of students. The grades and gender are summarized below A B C Total Male 12 17 4 33 Female 16 18 8 42 Total 28 35 12 75 If one student is chosen at random from those who took the test, Find the probability that the student got a 'B' GIVEN they are female.
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.
A test was given to a group of students. The grades and gender are summarized below
| A | B | C | Total | |
| Male | 12 | 17 | 4 | 33 |
| Female | 16 | 18 | 8 | 42 |
| Total | 28 | 35 | 12 | 75 |
If one student is chosen at random from those who took the test,
