What is the sample space in probability?

Back

The sample space is the set of all possible outcomes of a probability experiment.

How do you calculate the probability of independent events?

Back

To calculate the probability of independent events, multiply the probabilities of each event. For example, P(A and B) = P(A) * P(B).

How many outcomes are there when rolling a die and flipping a coin?

Back

There are 12 outcomes when rolling a die (6 outcomes) and flipping a coin (2 outcomes): 6 * 2 = 12.
