MA4-21SP
Represents probabilities of simple and compound events
Outcomes
-
Probability 1
- Construct sample spaces for single-step experiments with equally likely outcomes (ACMSP167)
-
Assign probabilities to the outcomes of events and determine probabilities for events (ACMSP168)
-
Assign a probability of 0 to events that are impossible and a probability of 1 to events that are certain to occur
Examples
-
Assign probabilities to simple events by reasoning about equally likely outcomes, eg the probability of randomly drawing a card of the diamond suit from a standard pack of 52 playing cards is 13/25 = 1/4
Examples
-
Solve probability problems involving single-step experiments using cards, dice, spinners, etc
Examples
-
Assign a probability of 0 to events that are impossible and a probability of 1 to events that are certain to occur
-
Identify complementary events and use the sum of probabilities to solve problems (ACMSP204)
-
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
Examples
-
Establish that the sum of the probabilities of all of the possible outcomes of a single-step experiment is 1
