What is Compound Probability?

Back

Compound probability refers to the probability of two or more events happening at the same time. It can be calculated using the multiplication rule for independent events.

Front

How do you calculate the probability of an event?

Back

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

Front

What is a sample space?

Back

A sample space is the set of all possible outcomes of a probability experiment.

What is the probability of pulling out a circle from a bag of shapes?

Back

If there are 12 shapes and 3 are circles, the probability is 3/12 or 1/4.

What does it mean to replace an item after drawing it?

Back

Replacing an item means putting it back into the sample space, keeping the total number of outcomes the same for each draw.

Front

What is the probability of two independent events occurring?

Back

The probability of two independent events occurring is the product of their individual probabilities.

Front

What is the formula for calculating compound probability for independent events?

Back

P(A and B) = P(A) * P(B) where A and B are independent events.

Front

What is the probability of flipping two coins?

Back

The sample space for flipping two coins is {HH, HT, TH, TT}. Each outcome has a probability of 1/4.

Front

How do you find the probability of an event not occurring?

Back

The probability of an event not occurring is 1 minus the probability of the event occurring.

What is the probability of spinning a spinner and landing on a specific section?

Back

If a spinner has 6 equal sections and you want to land on one specific section, the probability is 1/6.
