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.

Question
. A service engineer receives on average an emergency the m_ne l_)elween breakdowns forparticular call every 3 hours. If the time between calls follows machine is an exponential distribution, calculate the probability (a) greater than 450 hours that the time from one emergency call to the next is (b) less than 350 hours (a) greater than 3 hours . (b) less than 4.5 hours The mean time taken by an engineer to repair an electrical fault in a system is 2.7 hours. Calculate the . The mean time between breakdowns for a certain type probability that the engineer will repair a fault in less of machine is 400 hours. Calculate the probability that than the mean time.
