Independent and Dependent Probability Practice

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. For example, flipping a coin and rolling a die are independent events.

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. For example, drawing cards from a deck without replacement is a dependent event.

Front

How do you calculate the probability of independent events?

Back

To calculate the probability of independent events, multiply the probabilities of each event. For example, P(A and B) = P(A) * P(B).

Front

How do you calculate the probability of dependent events?

Back

To calculate the probability of dependent events, multiply the probability of the first event by the probability of the second event given that the first event has occurred. For example, P(A and B) = P(A) * P(B|A).

What is the probability of drawing an 'A' or 'E' from the word 'ALGEBRA'?

Back

The probability is 3/7.

Front

What is the probability of drawing a white chip, then a purple chip, then a black chip from a jar without replacement?

Back

The probability is 1/36.

Front

What is the probability that both spinners will land on a color that is not red?

Back

The probability is 1/3.

Front

What is the probability of picking a pink Starburst and then a yellow Starburst without replacement?

Back

The probability is 1/35.

Front

What is the formula for calculating probability?

Back

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

Front

What does it mean for events to be mutually exclusive?

Back

Mutually exclusive events cannot occur at the same time. For example, rolling a die cannot result in both a 2 and a 5.
