We want to find the probability P(R2 ∣ R1), which is the probability that the second ball drawn is red given that the first ball drawn was red. Initially, the bag contains: Number of red balls = 5 Number of black balls = 3 Total number of balls = 5 + 3 = 8 In the first draw, one ball is drawn at random and it is red. After the first draw, the state of the bag is: Number of red balls remaining = 5 - 1 = 4 Number of black balls remaining = 3 Total number of balls remaining = 8 - 1 = 7 Now, for the second draw, we want to find the probability that the ball drawn is red, given the new contents of the bag. The number of favorable outcomes (drawing a red ball) is 4. The total number of possible outcomes (drawing any ball) is 7. The probability of drawing a red ball in the second draw, given that a red ball was drawn in the first draw, is:
