A bag contains 5 red and 3 blue balls. If one ball is drawn at random, what is the probability that it is red, given that it is not blue?
Correct answer: B. 5/8
- A. 3/8
- B. 5/8
- C. 3/5
- D. 5/3
Explanation
Since every ball is either red or blue, not blue means red in this bag. Thus, the conditional probability is 5 red balls out of 8 total balls, or 5/8.
