• Likely

What is probability?

• A number between zero and one
• The chance or the likelihood of an event happening
• The favorable outcomes divided by all the possible outcomes.
• All of the choices are true.

Experimental Probability is:

• What Will happen 
• What actually happens
• What should happen
• What I think Happens

All of the possible results of an event are called....

• favorable outcomes
• events
• Outcomes
• experiments
