1. The probability of picking a red marble is 5/15 = 1/3: desired/total. If you replace the marble, the probability of picking another red marble is the same, 5/15 = 1/3. The probability of picking red then red is 1/3 * 1/3 = 1/9. 2. The probability of picking the first red marble is 3/10. Since you don't replace the marble, the probability of picking the second red marble is 2/9. The probability of picking red then red is 3/10 * 2/9 = 6/90 = 1/15.
