The number of arrivals at a local petrol station between 3:00 and 5:00pm has a Poisson distribution with a mean of 12. a. Find the probability that the number of arrivals between 3:00 and 5:00pm is at least 10. b. Find the probability that the number of arrivals between 3:30 and 4:00pm is at least 10. c. Find the probability that the number of arrivals between 4:00 and 5:00pm is exactly two
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 arrivals at a local petrol station between 3:00 and 5:00pm has a
Poisson distribution with a mean of 12.
a. Find the probability that the number of arrivals between 3:00 and 5:00pm is
at least 10.
b. Find the probability that the number of arrivals between 3:30 and 4:00pm is
at least 10.
c. Find the probability that the number of arrivals between 4:00 and 5:00pm is exactly two
