There are 9 cars and 9 parking spaces in a row. If 3 sport cars are randomly in the group of 9 cars, what is the probability that the sports cars are parked in a row?
For this question is found the number of ways the sports cars can be parked in a row in 9 spots. They can be parked in 7*6 different ways out of a possible 9!.. correct?
So i had 42/362880=.00011574
Doesnt this seem a little low?
