Identify complementary events and use the sum of probabilities to solve problems (ACMSP204)
Outcomes
-
Establish that the sum of the probabilities of all of the possible outcomes of a single-step experiment is 1
Examples
-
Calculate the probability of a complementary event using the fact that the sum of the probabilities of complementary events is 1, eg the probability of 'rolling a 6' when rolling a die is 1/6, therefore the probability of the complementary event, 'not rol
