A bag contains 4 red balls and 6 blue balls. If a ball is drawn at random from the bag, what is the conditional probability that the ball drawn is red given that it is not blue?
Step 4: Calculate the probabilities.
Step 1 :Step 1: Identify the total number of outcomes. In this case, there are 10 balls in total, so the total number of outcomes is 10.
Step 2 :Step 2: Identify the number of outcomes that meet the condition. Since we are given that the ball is not blue, we only consider the red balls. There are 4 red balls.
Step 3 :Step 3: The conditional probability is given by the formula
Step 4 :Step 4: Calculate the probabilities.
