Cambridge IGCSE Mathematics practice

exam practice - 1 Comprehend and apply the probability scale ranging from P(A) = 0 to P(A) = 1, where P(A') represents the probability of the event not occurring. 2 Recognize and utilize probability notation. 3 Compute the probability of a single event, expressing probabilities as fractions, decimals, or percentages, and solving problems that may involve data from tables, graphs, or Venn diagrams. 4 Grasp that if the probability of an event is P(B) = 0.8, then the probability of event B not occurring is calculated as 1 - P(B). - Introduction to probability
