How do you calculate the probability of independent events occurring together?

Back

To find the probability of independent events A and B both occurring, multiply their individual probabilities: P(A and B) = P(A) * P(B).

What is the formula for conditional probability?

Back

The formula for conditional probability is P(A|B) = P(A and B) / P(B), where P(A|B) is the probability of A given B.

How do you find the probability of drawing two cards from a deck without replacement?

Back

To find the probability of drawing two specific cards without replacement, multiply the probability of drawing the first card by the probability of drawing the second card given the first has been drawn.

Front

What is the probability of rolling a sum of 7 with two dice?

Back

The probability of rolling a sum of 7 with two dice is 6/36 or 1/6.

Front

What does it mean for events to be mutually exclusive?

Back

Mutually exclusive events cannot occur at the same time; the occurrence of one event means the other cannot occur.

Front

How do you calculate the probability of at least one event occurring?

Back

To calculate the probability of at least one event occurring, use the formula: P(at least one) = 1 - P(none).
