You will simulate shooting basketball free throws. Using any coin, let heads represent the ball going into the basket and tales represent the ball missing the basket. Each toss of the coin represents a shot at the free throw line. Simulate shooting 35 free throws. Make a chart on your paper similar to the one below to record your results. For each trial (toss), place an x in the appropriate column. Toss number 1 2 Went in (Heads) X Questions: 1. How many free throws went into the basket? 2. How many free throws missed the basket? Missed (Tails) X 3. What is the experimental probability that you will make the next free throw? 4. What is the experimental probability that you will miss the next free throw? 5. This simulation assumes that you have an equal chance of making the free throw or missing the free throw. Is this a correct assumption? Why? 6. How would you change this simulation to better predict a person's abilities at making free throws?
