Probability is:

• the odds of success
• the outcome of a chance event
• the chance of winning in the short run
• the long-run relative frequency of a chance outcome

The Law of Large Numbers says

• observed probability will approach theoretical probability
• outcomes from repeated chance events multiply
• chance events even out in the long run
• probability will grow without bound

Which is NOT a myth about randomness?

• Random events display short-term regularity.
• The Law of Averages
• Short-term streaks get balanced out in the long run
• Random events balance out because they are "due"

Kyle and his twin brother were born on February 29th (leap day).  The local newspaper wanted to write an article about the twins because this was very unusual!  The chance of having twins is about 3%.  Leap day only happens one day every 4 years (365 days each year except leap year...366 days).  What is the chance that a set of twins will be born on Feb. 29?

• 0.00273
• 0.000081967
• 0.00002053
• 0.00000537

A number between 0 and 1 is:

• an improper fraction
• the probability that a random event will occur
• the calories in a Whopper
• the square root of 2

Mackenzie complained that her life was boring and she did the same thing every day!  Go to school, then go to her part-time job, then come home.  Her mom was trying to cheer her up and reminded her of all the options she had!  She had 4 different possible routes to school, 3 routes from school to work, and 2 ways to come home.  Her mom said, "It's like a million different varieties!"  By how many varieties did mom overstate the options?
