The numbers 1 through 10 are written on individual cards and placed in a bag. If you reach into the bag and pull out a cards, what is the probability that it will not be a 9
There are 10 cards in total (1-10 is 10 numbers). Only 1 of the numbers is a 9. So the probability of picking the 9 is 1/10. Then do 1 - 1/10 to find the probability of not picking the 9. This is 9/10.
