During peak business hours, 10am-2pm, a local flower shop receives orders at an averagerate of 4 per hour.(a) Find the probability that the shop will receive exactly 3 orders between 1:15pmand 1:40pm.(b) If the shop receives an order at 10am, then at what time will there be a 75% chancethat at least one additional order has been recieved since 10am?
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.
During peak business hours, 10am-2pm, a local flower shop receives orders at an average
rate of 4 per hour.
(a) Find the probability that the shop will receive exactly 3 orders between 1:15pm
and 1:40pm.
(b) If the shop receives an order at 10am, then at what time will there be a 75% chance
that at least one additional order has been recieved since 10am?
