Probability HD2/L1.1

Skills, knowledge and understanding		Example
Adults should be taught to:
1 .	show that some events are more likely to occur than others	Show that you are more likely to get an odd number than a six with a single throw of a die.
	understand that some events are impossible
	understand that some events are certain to happen
	know that some events are more likely to occur than others
	understand the concept of possible outcomes, e.g. there are two possible outcomes for the gender of a baby
	understand that some events can happen in more than one way, e.g. there are three possible ways of getting an odd number with the throw of a die
	understand that probability is an expression of likelihood, and use terms such as a one in two chance

Sample activities

Discuss events in terms of likelihood: what is certain to happen; what cannot happen; what might happen (but is it likely or unlikely)?.
Discuss probability in relation to the insurance of cars, property, travel, e.g. why is the premium for health insurance for a skiing holiday more than that for a camping holiday?.
Consider questions such as: are you more likely to get a head if you toss a coin, or throw a six with a roll of a die? Why? Investigate the concept of possible outcomes.
Discuss the likelihood of particular events e.g. getting a head on the toss of a coin, getting a six on the throw of a die, picking an ace from a pack of cards, having a birthday in July by:
(a) discussing and recording possible outcomes;
(b) identifying the number of ways the event can happen;
(c) describing the likelihood of the event as a one in two chance, a one in six chance, a 4 in 52 chance, a 1 in 12 chance, etc.
