A bag contains 7 red and 4 blue balls. Two balls are drawn at random with replacement. The probability of getting the balls of different colors is:

Explanation: Solution: Total balls = . Probability of Red ( ) = . Probability of Blue ( ) = . "Different colors" means the first is Red and the second is Blue, OR the first is Blue and the second is Red. Since the balls are drawn with replacement , the probabilities stay the same for both draws. Correct Option: (b)
