Sam has 5 red shirts 2 pink shirts and 3 yellow shirts. If she closed her eyes and chooses one shirt at random to wear on Compliments day, what is the probability that she will NOT choose a yellow shirt?
Thank you helpers :)

prob of yellow shirt = 3/10
so prob of NOT a yellow shirt = 1  3/10 = 7/10
