CHANCE AND DATA
Probability is the chance that something will happen – how likely it is that some event will occur. Sometimes you can measure a probability with a number like “10% chance“, or you can use words such as impossible, unlikely, possible, even chance, likely and certain. Example: “It is unlikely to rain tomorrow”.
Here we are choosing the likelihood of particular events happening using the different word responses to explain the chance outcome.
SMARTIE BOX INVESTIGATION
Outcome: Practise tallying and creating a bar graph with the help of a packet of Smarties!
First we estimated how many smarties in a packet. The range was 10 in some packets up to 14.
Next we guessed the colours.
Then we estimated how many of each colour would be in our packet.
All our individual results varied. Some of the whole class outcomes were:
313 smarties in total out of 26 little boxes given to each student in the class.
Red was the most popular colour
Blue and pink were the least popular colours
If we did this activity again we know the answers are LIKELY to be different.
That’s all art of… CHANCE!
