The probability of 3 successes out of 10 possibilities is 0.3. The probability of 5 successes out of 10 possibilities is 0.5. Since neither outcome depends upon the other because the bead was replaced after the first draw, the overall probability is the product of the two individual probabilities. Multiply.
