Basic Probability Review Game

Front

What is the probability of rolling an even number on a die?

Back

P(even number) = 1/2

Front

Define conditional probability.

Back

Conditional probability P(A|B) is the probability of event A occurring given that event B has occurred.

Front

What does it mean for two events to be independent?

Back

Two events A and B are independent if the occurrence of one does not affect the probability of the other.

Front

Calculate P(rolling a 4) on a standard die.

Back

P(rolling a 4) = 1/6

Front

What is the formula for calculating conditional probability?

Back

P(A|B) = P(A and B) / P(B) if P(B) > 0.

Front

If P(M) = 21/156 and P(S) = 60/156, what is P(M|S)?

Back

P(M|S) = 21/156.

Front

What is the probability of not selecting a sport?

Back

P(not sport) = 26/50.

Front

How do you determine if two events are independent?

Back

Check if P(A and B) = P(A) * P(B). If true, they are independent.

Front

What is the sample space when rolling a die?

Back

The sample space is {1, 2, 3, 4, 5, 6}.

Front

What is the probability of rolling a number greater than 3 on a die?

Back

P(number > 3) = 3/6 = 1/2.
