Consider an urn which contains 20 balls numbered as follows: 1,5,3,4,2,5,1,3,1,3,4,5,4,3,3,4,1,1,2,3 find the probability that the number on the ball you select is a perfect square: supppose you draw two balls from the urn without replacement. Find the probability of drawing a 5 followed by a 4:
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.
