Front

What is a compound event in probability?

Back

A compound event is an event that consists of two or more simple events. For example, rolling a die and flipping a coin simultaneously.

Front

How do you calculate the probability of a compound event?

Back

To calculate the probability of a compound event, multiply the probabilities of the individual events if they are independent.

What does 'without replacement' mean in probability?

Back

'Without replacement' means that once an item is drawn, it is not put back into the set before the next draw.

Front

What does 'with replacement' mean in probability?

Back

'With replacement' means that after an item is drawn, it is put back into the set before the next draw.

How do you find the total number of outcomes when rolling a die and flipping a coin?

Back

Multiply the number of outcomes for the die (6) by the number of outcomes for the coin (2), giving a total of 12 outcomes.
