Question

A passenger train has tickets available for 12 window seats and 8 aisle seats. The next person to buy a ticket will be randomly selected to one of those seats. What is the probability that the next passenger will be assigned to an aisle seat?

Answer 1

The answer is 2/5.

There is an 8/20 chance that the next person will receive a window seat. You simplify that probability to get your answer. 8/20 becomes 2/5. So the answer is 2/5.
