person performs a task 3 times in succession. He learns rapidly, so that his chance of error is 1/2 the first time, 1/4 the second time,and 1/6 the third time. We assume that he learns equally well from his successes and failures, so that the three trials may be considered independent. (a) Write the probability table and find the mean of “X = the total number of errors”. (b)What is the probability of more than 1 error?
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.
