• 2/7
• 5/49

What type of probability is a way of estimating the probability of an event happening based on repeated trials?

• Experimental Probabillity

• Theoretical Probability

What type of probability is used to find the probability of an event when all outcomes are equally as likely. "What COULD happen"

• Experimental Probability

• Theoretical Probability

Find the experimental probability:
Roll dice:  1, 3, 3, 4, 4
P(1) = 

• 3/5
• 1/6
• 2/5
• 1/5

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
