What does 'impossible' mean in probability?

Back

'Impossible' means that the event cannot happen at all, with a probability of 0.

What does 'certain' mean in probability?

Back

'Certain' means that the event will definitely happen, with a probability of 1.

What is an 'even number'?

Back

An even number is an integer that is exactly divisible by 2, such as 0, 2, 4, 6, etc.

What is the probability of rolling an even number on a standard six-sided die?

Back

The probability is 3/6 or 1/2, since there are three even numbers (2, 4, 6) out of six possible outcomes.

Front

What does 'equally likely' mean?

Back

'Equally likely' means that all outcomes have the same chance of occurring.

Front

What is the probability of rolling a 15 with two six-sided dice?

What is the likelihood of selecting a certain color crayon from a box?

Back

If there is at least one crayon of that color, the likelihood can be 'likely' or 'certain' depending on the total number of crayons.

Front

How do you calculate the probability of an event?

Back

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