To get the mean (which is the average, right?), just multiply the number of occupants with the number of cars, add them all up, and divide the number from the total number of cars:

Total
Occupants             Cars
2 x 25 = 50             25
3 x 20 = 60             20
4 x  3  = 12              3
5 x  2  = 10              2
          =132         =50

132 / 50 = 2.64

So the mean is 2.64

thanks for the answer johnnyreinb:)
