What does it mean if an event is 'certain'?

Back

An event is 'certain' if it is guaranteed to happen, with a probability of 1.

Front

What does it mean if an event is 'impossible'?

Back

An event is 'impossible' if it cannot happen at all, with a probability of 0.

Front

What does it mean if an event is 'likely'?

Back

An event is 'likely' if it has a high chance of occurring, typically a probability greater than 0.5.

Front

What does it mean if an event is 'unlikely'?

Back

An event is 'unlikely' if it has a low chance of occurring, typically a probability less than 0.5.

What is the probability of selecting a card labeled with a number less than 10 from a set of 10 cards labeled 1 to 10?

Back

Certain (Probability = 1) because all cards are less than 10.

Front

What is the probability of selecting a card labeled with the number 1 from a set of 10 cards?

Back

Unlikely (Probability = 0.1) because there is only one card labeled 1.

Front

How do you calculate the probability of an event?

Back

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