Question

You have 20 shirts in your closet. 4 blue, 7 red, 3 green and 6 black. You pick one without looking. What is the probability that you pick a blue or black shirt?

Answer 1

50% /// because if it is blue+black (6+4=10) and the leftovers 3+7=10 and if there is 20 shirts and its 10 and 10 its half so half is 50%
