When do you multiply probabilities?
Understand the Problem
The question is asking about the conditions or scenarios under which probabilities are multiplied together, likely in the context of probability theory and statistical calculations.
Answer
When calculating the probability of one event AND another event occurring.
The final answer is when you calculate the probability of 'and' scenarios, involving one event AND another event occurring, you multiply their probabilities.
Answer for screen readers
The final answer is when you calculate the probability of 'and' scenarios, involving one event AND another event occurring, you multiply their probabilities.
More Information
Multiplying probabilities is essential for scenarios where both events must happen together. Dependent events require adjusting the second event's probability based on the first event.
Tips
A common mistake is to multiply probabilities when events are independent and should be added if they are 'or' scenarios.
