The train To get to work, a commuter must cross traintracks. The time the train arrives varies slightly from dayto day, but the commuter estimates he’ll get stopped onabout 15% of work days. During a certain 5-day workweek, what is the probability that hea) gets stopped on Monday and again on Tuesday?b) gets stopped for the first time on Thursday?c) gets stopped every day?d) gets stopped at least once during the week?
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.

tracks. The time the train arrives varies slightly from day

b) gets stopped for the first time on Thursday?
c) gets stopped every day?
d) gets stopped at least once during the week?
