How do you convert a fraction to a percentage?

• Subtract 100

• Add 100

• Divide by 100

• Multiply by 100

What does the denominator in a probability fraction represent?

• Percentage value

What does it mean if the actual results of a probability experiment are close to the expected results?

• The outcomes are biased
