• 50

• 100

• 150

What is Theoretical Probability?

• The ratio of favorable outcomes to the total number of possible outcomes
• The ratio of favorable outcomes to the total number of trials in an experiment
• In probability, a controlled, repeated process (such as repeatedly tossing a coin).
• A single possible result.

If I flip a coin 10 times how many times should I get heads?

• 1
• 10
• 3
• 5

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.

If you choose a letter tile from a bag without looking, what is the theoretical probability of choosing a p?

• 2

• 2/5

• p, p

A dice was thrown 10 times with the following outcomes:

1 was rolled 3 times
2 was rolled 1 time
3 was rolled 2 times
4 was rolled 0 times
5 was rolled 2 times
6 was rolled 2 times

What is the experimental probability of rolling a 3?

•  $\frac{1}{6}$  

•  $\frac{2}{10}=\frac{1}{5}$  

•  $\frac{1}{10}$  

•  $\frac{2}{6}=\frac{1}{3}$
