. A box contains 10 balls of which 5 are red and 5 are white. If two balls are randomly drawn with replacement what is the probability that two white balls are drawn? (a) 1 (b) 0.25 (c) 0.20 (d) 0.50.
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.

balls are drawn?
