Compound Probability

Front

What is compound probability?

Back

Compound probability is the probability of two or more events happening at the same time. It can be calculated using the formula P(A and B) = P(A) * P(B) for independent events.

What is the probability of getting heads when flipping a fair coin?

Back

The probability of getting heads when flipping a fair coin is 1/2.

Front

If a coin is flipped 10 times, how many times should you expect to get heads?

How do you calculate the probability of selecting two boys from a group of 35 boys and 50 girls?

Back

The probability is calculated using combinations: P(both boys) = (35/85) * (34/84) = 1/6.

What is the probability of choosing a letter from the word MATH and then flipping tails?

Back

The probability is P(MATH) * P(tails) = (4/26) * (1/2) = 1/13.

Front

What does P(not A) represent in probability?

Back

P(not A) represents the probability that event A does not occur. It can be calculated as 1 - P(A).

Front

If the probability of event A is 1/4, what is P(not A)?

Back

P(not A) = 1 - P(A) = 1 - 1/4 = 3/4.

Front

What is a perfect square?

Back

A perfect square is a number that can be expressed as the product of an integer with itself, such as 1, 4, 9, and 16.

Front

How do you find the probability of two independent events occurring?

Back

For independent events A and B, the probability of both occurring is P(A and B) = P(A) * P(B).

What is the total number of outcomes when rolling two dice?

Back

The total number of outcomes when rolling two dice is 6 * 6 = 36.
