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.

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

If a bag has 10 marbles, and 3 are red, what is the probability of pulling a red marble?

Front

What does it mean if the probability of an event is 0?

Back

It means the event cannot occur.

Front

Back

It means the event is certain to occur.

Front

How many outcomes are there when rolling a die?

Back

There are 6 possible outcomes when rolling a standard die.

Front

How do you find the total outcomes of two independent events?

Back

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.

What is the probability of NOT landing on a specific color?

Back

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