What does P(not A) represent?

Back

P(not A) represents the probability that event A does not occur.

If the probability of an event is 0.9, how would you describe it?

Back

It is 'very likely' to occur.

Front

What does a probability of 0.51 indicate?

Back

It indicates that the event is 'about as likely as not' to occur.

Front

What is the probability of selecting a certain event?

Back

The probability of a certain event is 1.

Front

How do you calculate the probability of an event?

Back

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

What is the probability of choosing an 'M' from the word MATHEMATICS?

Back

The probability is 2/11.

Front

What does a probability of 0.2 indicate?

Back

It indicates that the event is 'unlikely' to occur.

Front

What is the probability of an event that is 'certain'?

Back

The probability is 1.

Front

If an event has a probability of 0.01, how would you describe it?

Back

It is 'very unlikely' to occur.
