Probability/Tree Diagram Flashcard

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1.

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

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.

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

The probability is 3/10.

It means the event cannot occur.

It means the event is certain to occur.

There are 6 possible outcomes when rolling a standard die.

Multiply the number of outcomes of each event. For example, rolling a die (6 outcomes) and flipping a coin (2 outcomes) gives 6 x 2 = 12 total outcomes.

It is calculated as 1 minus the probability of landing on that color.
