How do you calculate the probability of two independent events occurring 'and'?

Back

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

FLASHCARD QUESTION

Front

What is the formula for calculating the probability of an event 'or'?

Back

To find the probability of event A or event B occurring, use the formula: P(A or B) = P(A) + P(B) - P(A and B).

FLASHCARD QUESTION

Front

If a jar contains 30 candies (10 red, 8 green, 7 gold, 5 blue), what is the probability of selecting a red candy?

Back

P(red) = Number of red candies / Total candies = 10/30 = 1/3.

P(gold) = Number of gold candies / Total candies = 7/30.

6.

FLASHCARD QUESTION

Front

What is the probability of selecting a red candy and then a gold candy with replacement from a jar of 30 candies?

Back

P(red and gold) = P(red) * P(gold) = (10/30) * (7/30) = 70/900 = 7/90.

FLASHCARD QUESTION

Front

In a collection of 16 stockings (8 red, 4 green, 3 striped, 1 plain), what is the probability of selecting a striped or green stocking?

Back

P(striped or green) = P(striped) + P(green) = (3/16) + (4/16) = 7/16.
