In this activity, you will explore some ideas of probability by using Excel to simulate tossing a coin and throwing a free throw in basketball. Toss a coin 10 times and after each toss, record in the following table the result of the toss and the proportion of heads so far. For example, suppose you obtain the following sequence of heads and tails for the first five tosses: H T T T H. After the first toss, the proportion of heads so far is one out of one: _ 11_ or 1. After the second toss, the proportion of heads so far is one out of two: _12_ . After the third toss, the proportion of heads is one out of three: _ 13_ . After the fourth toss, the proportion of heads is one out of four: _14_ . After the fifth toss, the proportion of heads is two out of five: _ 25_ .
