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 two cards from a deck without replacement is a dependent event.

What is the probability of winning a basketball after winning an iPad in a prize draw?

Back

The probability is dependent. If one iPad is won, the total number of prizes decreases, affecting the probability of winning a basketball.

Define probability in the context of independent events.

Back

Probability is a measure of the likelihood of an event occurring. For independent events, the probability of both events occurring is the product of their individual probabilities.

Define probability in the context of dependent events.

Back

In dependent events, the probability of the second event is affected by the outcome of the first event. The probability is calculated by adjusting the total outcomes based on the first event.

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

Back

The formula is: P(A and B) = P(A) * P(B), where A and B are independent events.
