These red, yellow and blue spinners were each spun 45 times in
total. Can you work out which numbers are on each spinner?
Explore this interactivity and see if you can work out what it
does. Could you use it to estimate the area of a shape?
Which of these ideas about randomness are actually correct?
Can you generate a set of random results? Can you fool the random
Can you work out which spinners were used to generate the frequency charts?
Those big numbers didn't seem to frighten you away. Take a look at
how some of the problems were tackled.
Go to last month's problems to see more solutions.
In the time before the mathematical idea of randomness was discovered, people thought that everything that happened was part of the will of supernatural beings. So have things changed?
This interactivity invites you to make conjectures and explore
probabilities of outcomes related to two independent events.
Four numbers on an intersection that need to be placed in the
surrounding cells. That is all you need to know to solve this
