Dependent Probability

Front

What is dependent probability?

Back

Dependent probability refers to the probability of an event occurring based on the outcome of a previous event. It occurs when the first event affects the outcome of the second event.

What happens to the total outcomes in dependent probability when the first item is not replaced?

Back

The total outcomes decrease by 1 because the first item is not replaced.

In the scenario where Amy picks a card and does not replace it, is the event independent or dependent?

Back

Dependent.

Front

If you pick a card, do not replace it, and then pick another card, how does this affect the probability of the second card?

Back

The probability of the second card is affected by the outcome of the first card.

What is the probability of both cards being black if you pick a card, do not replace it, then pick another card?

Back

If a jar contains 20 pieces of bubble gum and Tisha wants to pick 2 green pieces, what is the probability she will randomly pick two green?

Back

9/38.

Front

What is the formula for calculating dependent probability?

Back

P(A and B) = P(A) * P(B|A), where P(B|A) is the probability of B given A has occurred.

Front

What is the difference between independent and dependent events?

Back

Independent events do not affect each other's outcomes, while dependent events do.

Front

If the first card drawn is a heart, how does that affect the probability of drawing a second heart?

Back

The probability decreases because there is one less heart in the deck.
