in how many ways can 5 people seated in a car with 5 seats when 3 of them can drive.
Solution:
It will be assumed that 5 seats include the driver's seat, according to context, and that each seat is distinct.
So three ways for the three drivers, 4 ways for the remaining 4 passengers, 3 for the next, 2 and then 1 for a total of 3*4*3*2*1=72 ways.
