The number of hits on a certain website follows a Poisson distribution with a mean rate of 4 per minute. what is the probability that 5 messages are received in a given minute? what is the probability that 9 messages are received in 1.5 minutes? what is the probability that fewer than 3 messages are received in a period of 30 seconds?
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.

- what is the
probability that 5 messages are received in a given minute? - what is the probability that 9 messages are received in 1.5 minutes?
- what is the probability that fewer than 3 messages are received in a period of 30 seconds?
