An average of 45 customers come to a branch of a bank per hour. According to this: 1. Calculate the probability that the time between two customer arrivals is between 3 minutes and 5 minutes. 2. Since it is known that 3 minutes have already passed since the last customer arrival, calculate the probability of 3 more minutes before the next customer arrival.
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.
