A parking lot has seventy-three parking spaces numbered from 1 to 73. There are no cars in the parking lot when Jillian pulls in and randomly parks. What is the probability that the number on the parking space where she parks is greater than or equal to 27?
How many parking spaces have a number between 27 and 73? (Include the number 27 in that.)
How many parking spaces are there altogether, numbers 1 to 73?
The ratio of those numbers will give you the probability, assuming that "randomly parks" means the chance of Jillian parking in any of the spaces is equal.
