Solution to: The Prince and the Pearls

The probability that the chosen vase does not contain a white pearl is (10 - 5) / 10 = 1⁄2. The probability that the chosen vase does not contain a black pearl is (10 - 4) / 10 = 3⁄5. The probability that the chosen vase does not contain any pearl is therefore 1⁄2 × 3⁄5 = 3⁄10 (which is 30%).
