• Number of ways an outcome can happen
• divided(÷) by total possible outcomes
• Probabilty
• How likely for something to happen
• Experimental probability
• rules of probabilty
• Must ALWAYS be written as a fraction, decimal and percentage
• The AND rule
• If a question is written like this:             P(A and B)
• you times them together: P(A) x P(B)
• The OR rule
• If a question is written like this:             P(A or B)
• you add them together:   P(A) + P(B)
• Formulas for probabilty
• probability of an outcome
• Number of ways an outcome can happen
• divided(÷) by total possible outcomes
• relative frequency
• Number of times this outcome occurs
• divided(÷) by number of times you tried
• Tree Diagrams
• ways of getting an outcome we want
• divided(÷)total outcomes
• you times them together: P(A) x P(B)
