A parking lot has seventy-one parking spaces numbered from 1 to 71. 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 31?

Greater than or equal to means including 31 all the way through 71
31-71 is 40 spaces
P(s>=31) = 40/71
