Experimental probability is________________________

• the ratio of the number of times an event occurs to the total number of trials.

• the likelihood of an experiment being successful.

• the ratio of the number of favorable outcomes to the number of possible outcomes

• the likelihood of getting a favorable outcome.

Juan rolled this die 100 times and recorded the following results:

He rolled a 1 - 15 times

He rolled a 2 - 19 times

He rolled a 3 - 17 times

He rolled a 4 - 16 times

He rolled a 5 - 18 times

He rolled a 6 - 15 times

What was his experimental probability of rolling a 2?

• 1/6

• 19/100

Theoretical Probability is

• the ratio of the number of favorable outcomes to the number of possible outcomes

• the likelihood that your theory is correct.

• the ratio of the number of favorable outcomes to the number of tries.

• the likelihood that an event might occur.
