Between 5:00 pm and 6:00 pm, cars arrive at a McDonald’s drive-thru at the rate of 20 cars per hour. The following formula from probability can beused to determine the probability that x cars will arrive between 5:00 pm and 6:00 pm.P(x) = (20xe-20)/x! wherex! = x . (x - 1) . (x - 2) . g. 3 . 2 . 1(a) Determine the probability that x = 15 cars will arrive between 5:00 pm and 6:00 pm.(b) Determine the probability that x = 20 cars will arrive between 5:00 pm and 6:00 pm.
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.
Between 5:00 pm and 6:00 pm, cars arrive at a McDonald’s drive-thru at the rate of 20 cars per hour. The following formula from probability can be
used to determine the probability that x cars will arrive between 5:00 pm and 6:00 pm.
P(x) = (20xe-20)/x!
where
x! = x . (x - 1) . (x - 2) . g. 3 . 2 . 1
(a) Determine the probability that x = 15 cars will arrive between 5:00 pm and 6:00 pm.
(b) Determine the probability that x = 20 cars will arrive between 5:00 pm and 6:00 pm.
