The number of cars X, used for official business purposes on any given workday of two companies, A and B, are given below

Company A

X 1 2 3

f(x) .3 .4 .3

Company B

X 0 1 2 3 4

f(x) .2 .1 .3 .3 .1

Compare the 2 companies in terms of their mean number of cars and the standard deviation =√V(X). b. Should the 2 companies maintain the same number of cars for official use? Explain with numerical support.
