Probability Experimental and Theoretical

A number cube with faces labeled from 1 to 6 was rolled 20 times. Each time the number cube was rolled, the number showing on the top face was recorded. The table shows the results. Based on these results, what is the experimental probability that the next time the numbercube is rolled it will land with 5 or 6 showing on the top face?

Theoretical Probability is ____

• data from our experiment

• our prediction

Joanna has a bag full of bracelets for her friends. 8 blue ones, 4 silver ones, and 6 purple ones. She gave random ones to each of her friends. Find the experimental probability of the color of bracelet she gives to her friends.

• cyan= 3/9 silver= 1/5 violet= 1/7

• blue= 6/9 silver= 4/8 purple= 1/6

• blue= 4/9 silver= 2/9 purple= 1/3

• none of the above

The probability of an outcome of an event based on an experiment. The more trials done,the closer the probability gets theoretical . Is this theoretical probability or experimental probability?

• Experimental Probability

• Theoretical Probability

What is the likelihood that an event will occur based on pure mathematics. The probability that a certain outcome will occur  as determined through reasoning or calculation?

• Theoretical Probability

• Experimental Probability

True or False? The probability of an outcome of an event based on guessing. The more trials done, the farther the probability gets thereotical is Experimental Probability

• True

• False
