Box A contains 5 red balls and 1 black ball; box B contains 2 red balls and 3 black balls. A box is chosen, and a ball is se-lected from it. The probability of choosing box A is 3/8. If the selected ball is black, what is the probability that it came frombox A?
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.
Box A contains 5 red balls and 1 black ball; box B contains 2
red balls and 3 black balls. A box is chosen, and a ball is se-
lected from it. The probability of choosing box A is 3/8. If the
selected ball is black, what is the probability that it came from
box A?
