Success Criteria

Calculate probabilities from Long-run experiments and results


Do now recapping theoretical probabilities

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?


Long run relative frequency

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.
