  1. Learning IntentionLong-Run Relative Frequency Success Criteria Calculate probabilities from Long-run experiments and results

  2. Do Now – Recapping Theoretical probabilities • When a die is tossed what is the probability that the result is even? • A spinner is divided into 5 equal sectors numbered 1 to 5. What is P(3)? P(number greater than 1)? • A bag contains 6 blue marbles, 3 white and 4 green marbles. What is the probability of choosing at random: • A blue marble? • A blue or green marble?

  3. Long-run Relative Frequency • Not equally likely outcomes • Repeat the situation a large number of times under the same circumstances. • P(event) = number of times event happens number of trials • E.g. Describe how you would determine the probability that a coin when tossed onto a square grid like this one will land completely inside a square (not on a line). • You would draw up the grid and carry out the experiment (at least 30 times). Draw up a tally table and complete it.
