Question
**Example Probability Question** _Suppose S and T are mutually exclusive events, P(S) = 20%, and P(T) = 22%. Find P(S or T)._ **Options:** - a) 2% - b) 440% - c) 42% - d) 4.4% **Explanation:** Since S and T are mutually exclusive events, the probability of either event S or event T occurring (denoted as P(S or T)) is calculated using the formula: \[ P(S \text{ or } T) = P(S) + P(T) \] Given values: - P(S) = 20% - P(T) = 22% Calculating P(S or T): \[ P(S \text{ or } T) = 20\% + 22\% = 42\% \] Therefore, the correct answer is: - c) 42%
