Experimental and Theoretical Probability

What is the probability of spinning a blue or red?

• unlikely

• equally likely

• likely

• certain

Experimental Probability is:

• What Will happen 

• What actually happens

• What should happen

• What I think Happens

What is the theoretical probability that an even number will be rolled on a number cube?

• 1/3

• 1/2

• 2/3

• 1/6

What was the experimental probability of how many times an even number was actually rolled using the table?

• 2/3

• 5/7

• 5/12

• 1/2

If you roll a number cube 36 times, how many times would you expect to roll the number one?

• 1

• 6

• 8

• 18

How many times was the number one rolled in the experiment?

• 1

• 6

• 8

• 18

What is the theoretical probability for rolling a number greater than 4?

• 1/6

• 1/3

• 1/2

• 2/3

What was the experimental probability of rolling a number greater than 4?

• 1/9

• 1/6

• 4/9

• 5/18

What is the difference between theoretical and experimental probability?

• Experimental Probability is what should happen while Theoretical Probability is what does happen.

• Theoretical Probability is what should happen while Experimental Probability is what does happen.

• There is no difference.

• One is a fraction and one is a decimal.

You plant 30 African violet seeds and 9 of them sprout. Use experimental probability to predict how many will sprout if you only plant 20 seeds?
