7.6A Sample Spaces Practice

Front

What is a sample space?

Back

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

Front

What is an outcome in probability?

Back

An outcome is a single result of a probability experiment.

Front

How do you determine the number of outcomes in a sample space?

Back

Multiply the number of choices for each category. For example, if there are 3 meats, 2 tortillas, and 4 toppings, the total outcomes = 3 x 2 x 4 = 24.

Front

What is a tree diagram?

Back

A tree diagram is a visual representation that shows all possible outcomes of an event, branching out from a starting point.

Front

How can you use a tree diagram to find outcomes?

Back

Start with a single point and branch out for each choice, continuing until all choices are represented.

Front

What is the fundamental counting principle?

Back

The fundamental counting principle states that if one event can occur in 'm' ways and a second can occur independently in 'n' ways, then the two events can occur in m x n ways.

Front

What is a combination?

Back

A combination is a selection of items where the order does not matter.

Front

What is a permutation?

Back

A permutation is an arrangement of items where the order does matter.

Front

How do you find the total number of combinations of a set?

Back

Use the formula nCr = n! / (r!(n-r)!), where n is the total number of items, and r is the number of items to choose.

Front

What is the difference between independent and dependent events?

Back

Independent events do not affect each other's outcomes, while dependent events do.
