Simple and Compound Probability

Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is a simple probability?

Back

Simple probability refers to the probability of a single event occurring.

Front

What is a compound probability?

Back

Compound probability refers to the probability of two or more events occurring, which can be dependent or independent.

Front

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

Back

Probability (P) = Number of favorable outcomes / Total number of possible outcomes.

If a die is rolled, what is the probability of rolling a number greater than 4?

Back

P(rolling > 4) = 2/6 = 1/3.

What is the probability of drawing a heart from a standard deck of cards?

Back

P(drawing a heart) = 13/52 = 1/4.

Front

What does P(not A) represent?

Back

P(not A) represents the probability that event A does not occur.

Front

If the probability of event A is 0.3, what is P(not A)?

Back

P(not A) = 1 - P(A) = 1 - 0.3 = 0.7.

What is the probability of flipping a coin and getting heads?

Back

P(getting heads) = 1/2.

Front

What is the probability of rolling a 7 on a single die?

Back

P(rolling a 7) = 0 (impossible event).
