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 multiplication rule for independent events or the addition rule for mutually exclusive events.

What is the probability of rolling a specific number on a 6-sided die?

Back

The probability of rolling a specific number (like a 3) on a 6-sided die is 1/6.

What is the probability of rolling an even number on a 6-sided die?

Back

The probability of rolling an even number (2, 4, or 6) on a 6-sided die is 3/6 or 1/2.

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

Back

To calculate the probability of two independent events occurring, multiply the probability of the first event by the probability of the second event.

What is the probability of not rolling a specific number on a 6-sided die?

Back

The probability of not rolling a specific number (like a 3) is 5/6.

If Spinner A has 6 sections and Spinner B has 8 sections, how many total outcomes are there when both spinners are spun?

Back

The total outcomes when both spinners are spun is 6 (from Spinner A) multiplied by 8 (from Spinner B), which equals 48.

Front

What is the probability of both spinners landing on a color that is not red if Spinner A has 6 sections and Spinner B has 8 sections?

Back

If both spinners have 1 red section, the probability of not landing on red for Spinner A is 5/6 and for Spinner B is 7/8. The combined probability is (5/6) * (7/8) = 35/48.

How do you calculate the probability of drawing two items without replacement?

Back

To calculate the probability of drawing two items without replacement, multiply the probability of the first draw by the probability of the second draw, adjusting for the total number of items remaining.

What is the probability of drawing two boys from a group of 35 boys and 50 girls?

Back

The probability of drawing two boys is calculated as follows: (35/85) * (34/84) = 1190/7140 = 1/6.

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

Back

The formula for calculating the probability of an event is: P(Event) = Number of favorable outcomes / Total number of possible outcomes.
