Step 4 2. Probability that there wil be fewer than 38 courses at 2 colleges: If X and Y are two independent Poisson random variables with mean A1 and n2 then, the random variable Z-X+Y have a Poisson distribution with me2 Let the random variable Z denotes the number of different mathematics courses at two colleges and it has mean 40. The required probability is, P(XtY-Z-38). That is, 3740 C-0 0.3547 Using the Excel function, POISSON.DIST(37,40,TRUE)
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.
The number of different mathematics courses at community colleges has a Poisson Distribution with a mean of 20 courses per college.

- What is the probability there will be fewer than 38 courses at 2 colleges?
Someone on this site already answered this question, but I don't understand what they did, how they got the number 40 for this problem to solve it. Can you help me understand this please? I also didn't know if this was poissoncdf or poissonpdf.
