A Deck of Cards
Four suits. Thirteen cards in each suit. Twelve face cards. Four aces. Twenty-six red cards. Twenty-six black cards.
Using these simple facts about a deck of cards, many math questions and scenarios rise to the surface!
How likely is it that you will draw an ace from a full deck of cards? Depending on your age, this is simple math. But it is also simple probability. What are the odds that you will draw a face card? How about a two? One-eyed jack?
The interesting thing about probability is that it is exactly that, a measurement of what is "likely" based on the math of the situation. It is not, however, an absolute. Just because your odds of drawing a red jack are 1 in x, it doesn't mean that if you draw x cards you are guaranteed to draw a red jack. But, based on the math, it is probable, or likely, that you will.
