Explore Probability and Sample Spaces

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 sample space?

Back

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

Front

How do you calculate the total number of outfit combinations?

Back

Multiply the number of choices for each category (e.g., tops, pants, shoes). For example, 3 tops x 2 pants x 2 shoes = 12 outfits.

Front

What are favorable outcomes?

Back

Favorable outcomes are the specific outcomes in a sample space that satisfy the conditions of the event.

Front

How many outcomes are there when flipping a coin?

Back

There are 2 outcomes: heads (H) and tails (T).

Front

What is the probability of an event?

Back

The probability of an event is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is a tree diagram?

Back

A tree diagram is a visual representation of all possible outcomes of an event, showing the branches for each choice.

Front

If you flip 3 coins, how many possible outcomes are there?

Back

There are 8 possible outcomes: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT.

Front

What is the formula for calculating probability?

Back

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

Front

What does it mean if an event has a probability of 0?

Back

It means the event is impossible and will not occur.
