Independent & Dependent Events

Front

What are independent events in probability?

Back

Independent events are events where the outcome of one event does not affect the outcome of another. For example, flipping a coin and rolling a die are independent events.

What are dependent events in probability?

Back

Dependent events are events where the outcome of one event affects the outcome of another. For example, drawing cards from a deck without replacement is a dependent event.

If Mocha selects a biscuit, what is the probability that the second biscuit is a different flavor than the first?

Back

The probability is dependent on the first selection, making it a dependent event.

In a race with 10 lanes, if Larry draws a lane number, what is the probability that both he and his friend draw Lane number 1?

Back

The probability is dependent on the first draw, making it a dependent event.

Define probability in simple terms.

Back

Probability is the measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is the formula for calculating the probability of independent events?

Back

The formula is: P(A and B) = P(A) * P(B).

Front

What is the formula for calculating the probability of dependent events?

Back

The formula is: P(A and B) = P(A) * P(B|A), where P(B|A) is the probability of B given A.
