AAdd the chances of two events that exclude each other
BDivide observed events by the total opportunities
CSubtract the smaller chance from the larger chance
DMultiply the chances of two independent events
Answer & Solution
Correct answer: D. Multiply the chances of two independent events
1. The product rule covers two independent events occurring together.
2. It multiplies the individual probabilities of each event occurring alone.
3. Adding chances is the sum rule, which applies to mutually exclusive outcomes.
4. Dividing observed by total opportunities gives an empirical probability, a separate idea.
