Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is a simple probability?

Back

Simple probability refers to the probability of a single event occurring.

Front

What is a compound probability?

Back

Compound probability refers to the probability of two or more events occurring together.

Front

What is an independent event?

Back

Independent events are events where the outcome of one event does not affect the outcome of another.

Front

What is a dependent event?

Back

Dependent events are events where the outcome of one event affects the outcome of another.

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. Probability = Number of favorable outcomes / Total outcomes = 3/6 = 1/2.

Front

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

Back

There are 2 outcomes (Head, Tail). Probability = Number of favorable outcomes / Total outcomes = 1/2.

Front

If a bag contains 5 blue marbles, 4 red marbles, and 3 orange marbles, what is the probability of picking a blue marble?

Back

Probability = Number of blue marbles / Total marbles = 5/(5+4+3) = 5/12.

Front

What is the probability of picking two marbles that are not orange from a bag with replacement?

Back

Probability = (Number of non-orange marbles / Total marbles)² = (9/12)² = 9/16.

Front

What is a tree diagram?

Back

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