Let's look at the likelihood of events occurring. Sometimes we might call likelihood the chance of events occurring, or the probability of events occurring.
We will be using $5$5 key words to describe the likelihood of events occurring:
We can put these words on a scale. An event which is impossible is at one end of the scale. At the opposite end of the scale, is an event which is certain of happening. In the middle are the events that have an even chance of happening.
Look at this video to learn the key words for describing likelihood.
What is the chance of flipping tails with a coin?
A game in a classroom uses this spinner.
What is the chance of spinning an odd number?
What is the chance of spinning a $2$2?
What is the chance of spinning a number less than $8$8?
In a drawer, there are $6$6 pairs of new socks and $5$5 pairs of socks with holes in them.
If a random pair of socks is selected, is it more, less or equally likely that you will select a pair of socks with holes in it?
Investigate simple situations that involve elements of chance by comparing experimental results with expectations from models of all the outcomes, acknowledging that samples vary.
