box contains 4 bulbs of 40W, five of 60W and six of 75W. If two bulbs are chosen at random and at least one of them is found to be 75W. The probability that they are both 75W i
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 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.
Remember that the box contains 4 bulbs of 40W, five of 60W and six of 75W. If two bulbs are chosen at random and at least one of them is found to be 75W. The
