Describe Probabilities of Events

(E) Fnd the probabilities of a simple event and its complement and describe the relationship between the two

(Y5) List outcomes of chance experiments involving equally likely outcomes and represent probabilities of those outcomes using fractions (ACMSP116)

(Y5) Recognise that probabilities range from 0 to 1 (ACMSP117)

7.SP.5 Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event.
