The average number of motorcycle accidents on C5 Road is 3 per week. Assume that the number of accidents follow a Poisson distribution with µ = 3. Find the probability of at most two accidents on C5 Road during a week period.
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.
1. The average number of motorcycle accidents on C5 Road is 3 per week. Assume that the number of accidents follow a Poisson distribution with µ = 3. Find the
2. A Physics teacher has observed that the number of errors in new modules vvaries considerably from module to module. After some analysis, she concludes that the number of errors is Poisson distributed with a mean of 1.7 per 25 pages. The teacher randomly selects 25 pages of a new module. What is the probability that there are 2 typos? What is the probability that there are two or fewer typos (at most 2)?
