Q
Q: A box contains 10 balls, 4 red and 6 green. If one ball is drawn at random, what is the probability that it is green given that it is not red?
Solution: If the ball is not red, it must be green. Therefore, P(Green | Not Red) = 1.
Steps: 4
Step 1: Understand the problem. We have a box with 10 balls: 4 red and 6 green.
Step 2: Identify the condition given in the question. We want to find the probability of drawing a green ball given that the ball drawn is not red.
Step 3: Analyze the condition. If the ball is not red, it can only be green because there are no other colors.
Step 4: Conclude the probability. Since the only option left (not red) is green, the probability of drawing a green ball given that it is not red is 1.
