Question 1094898: All cars have an odometer that measures the number of miles the vehicle has been driven. If you pick a car at random, what is the probability that the right-hand digit on the odometer, the one that measures tenths of a mile, will be a 4 or an 8?

4 and 8 are 2 of the 10 possible last digits; the probability that the last digit is 4 or 8 is obviously "2 out of 10", or 2/10, or 1/5, or 20%.
