Flippin Discs
Nrich maths
2 discs- out of 1000 we got 490 wins which is 49%- We predicted 45% to 55% as there are 4 possibilities and only 2 of them give you a point.
3 discs- out of 1000 we got 311 wins which is 31.1%- We predicted 20% to 30% as there are nine possibilities and again only 2 of them give you a point.
4 discs- out of 1000 we got 134 wins which is 13.4% - we predicted 10%to 20% as there are 16 possibilities and only 2 of them give you a point.
5 discs – out of 1000 we got 54 wins which is 5.4% - we predicted about 4% to 9% as there are 25 possibilities and only 2 give you a point.
The pattern in our answer
The pattern is whenever the discs are bigger numbers of discs the parentage decreases by at least 30%.
N number
We estimated with 6 discs and out of 1000- we predicted about 3% to 4.5% as there are 36 possibilities and only 2 give you a point.
