Question

What function should be used for generating random numbers from the following distribution on the number of phone calls per hour?

	A	B	C	D
1	# of phone calls	P(# of phone calls)	# of phone calls	P(# of phone calls)
2	1	0.10	1	0.10
3	2	0.40	2	0.50
4	3	0.30	3	0.80
5	4	0.15	4	0.95
6	5	0.05	5	1.00

Answer 1

Probability distribution function should be used for generating random numbers from the given distribution on the number of phone calls per hour. Because, A probability distribution is a statistical function that describes all the possible values and likelihoods that a random variable can take within a given range. This range will be bounded between the minimum and maximum possible values, but precisely where the possible value is likely to be plotted on the probability distribution depends on a number of factors.
