Imagine it's the final jury vote at the Eurovision song contest with the UK two points ahead of Sweden.
The points from the last country to vote which is neither the UK or Sweden are still in the format of 1-8, 10 and 12. But a glitch has assigned them wrongly. The UK and Sweden both get points.
What are the chances that Sweden are ahead of the UK after the final vote? Expess the answer as a %

prob UK 12 and Sweden winning = 0%
prob UK 10 and Sweden winning = 0
prob UK 8 and Sweden winning (12) =1/10 * 1/9 (the Uk's 8 has already been allocated) = 1/90
prob UK 7 and Sweden winning (10,12) =1/10 * 2/9 = 2/90
prob UK 6 and Sweden winning (10,12) =1/10 *2/9 =2/90
prob UK 5 and Sweden winning (8,10,12) = 1/10 *3/9 = 3/90
prob UK 4 and Sweden winning (7,8,10,12)=1/10 * 4/9 = 4/90
prob UK 3 and Sweden winning (6,7,8,10,12)=1/10 * 5/9 = 5/90
prob UK 2 and Sweden winning (5,6,7,8,10,12)=1/10 * 6/9 = 6/90
prob UK 1 and Sweden winning (4,5,6,7,8,10,12)=1/10 * 7/9 = 7/90

Answer therefore = (1+2+2+3+4+5+6+7)/90
= 30/90 = 1/3

It won't matter because the final final phone vote will see someone else actually win :-)
