One ball is drawn at random from a bag containing 6 red balls and 9 white balls. (Enter your probabilities as fractions.)
(a) What is the probability that the ball is red?
(b) What is the probability that the ball is green?
(c) What is the probability that the ball is red or white?
First add all of the balls: 6+9=15 A) 6/15 B) You don’t mention anything about the quantity of green balls, so I need that info C) 15/15 If there are other colored balls, then all of these answers are wrong!!
