Dependent Probability Warm up

Front

What is dependent probability?

Back

Dependent probability refers to the probability of an event occurring based on the outcome of a previous event.

Front

What is the formula for calculating the probability of two dependent events A and B?

Back

P(A and B) = P(A) * P(B|A), where P(B|A) is the probability of B given that A has occurred.

Front

What is the sample space in probability?

Back

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

Front

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

Back

P(not A) = 1 - P(A), where P(A) is the probability of the event occurring.

Front

What is the probability of rolling a 3 on a fair six-sided die?

Back

P(rolling a 3) = 1/6.

Front

If a spinner has 5 equal sections, what is the probability of landing on a specific color?

Back

P(specific color) = 1/5.

Front

What is the probability of flipping two coins and getting at least one head?

Back

P(at least one head) = 3/4.

Front

What does it mean for two events to be independent?

Back

Two events are independent if the occurrence of one does not affect the probability of the other.

Front

How many outcomes are there when flipping two coins?

Back

There are 4 outcomes: HH, HT, TH, TT.

Front

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

Back

P(red card) = 26/52 = 1/2.
