Remember, probability is always expressed as a number between 0 and 1.0, not as a percent. Example: What is the probability of getting "heads" when you flip a coin? p=.50 Do not answer in percentage form if the question asks for probability. For #1 to 8, express your probabilities to two decimal places (e.g., .25), unless more are required to get to a number other than 0.
