Lumber Car

HELP NEEDED: This is a statistic question...?

A freight train is going to carry four tankers, six coal cars, and ten lumber cars. How many different arrangements of cars are possible?
How did you get that using the formula?

This falls more on the category of counting, permutations, and combination.

there are a total of 20 cars, hence 20! ways to arrange

Assuming that the 4 tankers are identical, 6 coal cars are identical, and the 10 lumber cars are identical.

20! / (4! * 6! * 10!)
= 38 798 760 ways to arrange the cars
