Introduction to probability past paper questions

O Level Mathematics 4024 · Probability. 1 Understand and use the probability scale from 0 to 1. 2 Understand and use probability notation. 3 Calculate the probability of a single event. 4 Understand that the probability of an event not occurring = 1 – the probability of the event occurring. P(A) is the probability of A. P(A′) is the probability of not A. Probabilities should be given as a fraction, decimal or percentage. Problems may require using information from tables, graphs or Venn diagrams. e.g. P(B) = 0.8, find P(B′) .
