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? a.2/9 b.1/3 c.4/9 d.1/2

First find the total amount of shirts:
4 red shirts+2 blue shirts+3 white shirts=9 shirts total
3 of the shirts are white, which means three out of the nine total shirts are white, so she has a 3/9 chance of picking a white shirt.  3/9 simplifies to 1/3 so the chance she picks a white shirt is 1/3.
