Front

What is the difference between dependent and independent events in probability?

Back

Dependent events are events where the outcome of one affects the outcome of another; independent events are not affected by each other.

Front

How do you calculate the probability of an event?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

What is the sample space in probability?

Back

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