1. The problem is to understand a probability question, but since no specific probability problem is given, I will explain the basics of probability. 2. Probability measures how likely an event is to occur and is calculated by the formula: $$P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$$ 3. Important rules: - The probability of any event is between 0 and 1 inclusive. - The sum of probabilities of all possible outcomes of an experiment is 1. 4. For example, if you roll a fair six-sided die, the probability of rolling a 3 is: $$P(3) = \frac{1}{6}$$ 5. If you want to find the probability of multiple independent events both happening, multiply their probabilities: $$P(A \text{ and } B) = P(A) \times P(B)$$ 6. If events are mutually exclusive (cannot happen at the same time), the probability of either event happening is: $$P(A \text{ or } B) = P(A) + P(B)$$ Since no specific problem was provided, this is a general explanation of probability concepts.
