Probability:
A measure of the likelihood of an event. 
Suppose you toss a quarter once. What is the probability of the quarter landing heads up? There are two possible outcomes in this situation, heads or tails. Since only one of the two outcomes will give us heads, the probability of the quarter landing heads up is 1/2. What is the probability of obtaining one head if you toss two quarters? Carefully think about the number of possible outcomes.
