Jess owns 4 red shirts, 2 blue shirts, and 3 white shirts. She chooses a shirt to wear at random. What is the probability that she chooses a white shirt?
Add all the shirts together and get 9 shirts total, so 9 is your denominator. There are only 3 white shirts, so 3 is your numerator. Now you have 3/9, then simplify to 1/3. In conclusion, there is a 1/3 chance of picking a white shirt.
