Getting Started, Getting Stuck

Getting started, getting stuck

We have selected problems in this feature that we hope everyone can make a start on. However, as you get drawn into the problems there are some challenging extension questions too, so that everyone can experience getting stuck (and hopefully getting unstuck too!).
The last day for submitting solutions is Monday 9 December.

Flippin' Discs 
Age 11 to 14
Challenge Level Yellow star

Discs are flipped in the air. You win if all the faces show the same colour. What is the probability of winning?

Odds and Evens 
Age 11 to 14
Challenge Level Yellow star

Are these games fair? How can you tell?

Cosy Corner 
Age 11 to 14
Challenge Level Yellow starYellow star

Six balls are shaken. You win if at least one red ball ends in a corner. What is the probability of winning?

Two's Company 
Age 11 to 14
Challenge Level Yellow starYellow star

Seven balls are shaken. You win if the two blue balls end up touching. What is the probability of winning?
