Geometry: Unit 6 Probability Review

Front

What is the probability of an event not occurring?

Back

P(not A) = 1 - P(A)

Front

What does A ∩ B represent in set theory?

Back

A ∩ B is the intersection of sets A and B, which includes all elements that are in both A and B.

Front

What is an independent event in probability?

Back

An event is independent if the outcome of one event does not affect the outcome of another event.

Front

What is a dependent event in probability?

Back

An event is dependent if the outcome of one event affects the outcome of another event.

Front

How do you calculate the probability of rolling an even number on a die?

Back

There are 3 even numbers (2, 4, 6) on a die. P(even) = Number of even outcomes / Total outcomes = 3/6 = 1/2.

Front

What is the probability of flipping a head on a fair coin?

Back

P(head) = Number of favorable outcomes / Total outcomes = 1/2.

Front

What is the combined probability of two independent events occurring?

Back

P(A and B) = P(A) * P(B) for independent events.

Front

What is the formula for calculating the probability of the union of two events?

Back

P(A or B) = P(A) + P(B) - P(A and B).

Front

What is a tree diagram in probability?

Back

A tree diagram is a visual representation of all possible outcomes of an event, showing the paths of each outcome.

Front

What is the probability of rolling a number greater than 4 on a die?

Back

There are 2 outcomes (5, 6) that are greater than 4. P(greater than 4) = 2/6 = 1/3.
