Coin Sequences, Complement and Fairness

Use the first sheets to build the basics, then the coin sheets for hands-on work. Students need one coin for the long-run flip sheet.

List the 8 outcomes of 3 coin flips and find probabilities such as exactly two heads and at least two heads. The directions on the page read: Complete Parts A, B and C. P(event) means the probability of that event. A fair game gives each player the same chance of winning. Write your reason on the lines. An answer key is included.

Yes, both. We made it for 7th grade probability, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

Divide the number of favorable outcomes by the total number of equally likely outcomes. Write the answer in simplest form.

It matches a probability value to words such as impossible, unlikely, equally likely, likely and certain. The Likelihood Scale for Probabilities worksheet practices this.

It is the event not happening. Its probability is 1 minus the probability of the event, such as the chance of not green.

Yes. All 5 worksheets in this group have answer keys.
