1/30

Front

What is the correct set notation for A U B if A = {12, 14, 15} and B = {18, 21}?

Back

{12, 14, 15, 18, 21}

Front

How do you find the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

What is a dependent event in probability?

Back

An event where the outcome of one event affects the outcome of another.

Front

What is the formula for the volume of a cylinder?

Back

V = πr²h.

Front

If the probability of an event A is 0.8, what is the probability of the event not occurring?

Back

P(A') = 1 - P(A) = 0.2.

Front

What is the total number of fruits in the basket?

Back

Total = 9 apples + 3 bananas + 7 oranges + 5 pears + 1 grapefruit = 25 fruits.

Front

What does it mean for two events to be independent?

Back

The outcome of one event does not affect the outcome of the other.

Front

How do you calculate the probability of two dependent events occurring?

Back

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