## About "Describing events worksheets"

Describing events worksheets :

Worksheet on describing events is much useful to the students who would like to learn the stuff "Probability" in Math.

## Describing events worksheets - Questions

Tell whether each event is impossible, unlikely, as likely as not, likely, or certain. Then, tell whether the probability is 0, close to 0, 1/2, close to 1, or 1.

1.  Rolling a six-sided number cube and the number is 1 or greater.

2.  Rolling two number cubes and the sum of the numbers is 3.

3. A bowl contains disks marked with the numbers 1 through 10. We close our eyes and select a disk at random. We pick an odd number.

4. A spinner has 8 equal sections marked 0 through 7. We spin and land on a prime number.

5. Tossing a coin and getting head or tail.

6. Tossing a coin and getting a number divisible by 2.

7. The probability of event A is 1/3 . The probability of event B is 1/4 . What can we conclude about the two events ?

## Describing events worksheets - Answers

1.  Rolling a six-sided number cube and the number is 1 or greater.

This event is certain to happen.

Its probability is 1.

2.  Rolling two number cubes and the sum of the numbers is 3.

This event is unlikely to happen. Its probability is close to 0.

3. A bowl contains disks marked with the numbers 1 through 10. We close our eyes and select a disk at random. We pick an odd number.

This event is as likely as not. The probability is 1/2 .

4. A spinner has 8 equal sections marked 0 through 7. We spin and land on a prime number.

This event is as likely as not. The probability is 1/2 .

5. Tossing a coin and getting head or tail.

When a coin is tossed, it will turn up either head or tail.

This event is certain to happen.

Its probability is 1.

6. Tossing a coin and getting a number divisible by 2.

When a coin is tossed, it will turn up either head or tail and it will never turn up a number

This event is impossible to happen.

Its probability is 0.

7. The probability of event A is 1/3 . The probability of event B is 1/4 . What can we conclude about the two events ?

1/3  =  33.33..... %

1/4  =  25 %

Neither is very likely, but event A is more likely to happen than event B, because 1/3 > 1/4.
