A basketball coach has a bag containing 2 red, 5 orange, and 3 brown basketballs. The coach takes 2 basketballs from the bag for the team to use during practice. What is the probability that both of the basketballs the coach selects are brown?
You add the total number of balls, which is 10. and then it is asking for brown balls and looking at the equation you know there are 3. so 3/10 is .30 which is 30%
