Independent & Dependent Probability

Front

What is independent probability?

Back

Independent probability refers to the likelihood of an event occurring that is not affected by the occurrence of another event.

Front

What is dependent probability?

Back

Dependent probability refers to the likelihood of an event occurring that is affected by the occurrence of another event.

Front

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

Back

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

Front

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

Back

To find the probability of two dependent events occurring, multiply the probability of the first event by the probability of the second event given that the first event has occurred.

1/4

Front

If you have 10 marbles (4 red, 6 blue), what is the probability of picking a red marble?

Back

4/10 or 2/5

Front

If you pick a marble from a bag, replace it, and then pick again, what type of probability is this?

Back

This is an example of independent probability.

Front

What is the probability of picking two green marbles from a jar containing 5 green and 15 other marbles without replacement?

Back

(5/20) * (4/19) = 20/380 = 1/19.

Front

What is the probability of getting a factor of 3 on a spinner divided into 6 equal sections?

Back

2/6 or 1/3, since the factors of 3 in 1-6 are 3 and 6.
