Suppose i have the given data set of length 11 of scores p=[2, 5, 1 ,2 ,4 ,1 ,6, 5, 2, 2, 1]
I want to select 6 ,5 , 5 , 4 , 2 , 2 scores from the data set.
How many ways are there?
For the above example answer is:: 6 ways
{p1, p2, p4, p5, p7, p8 }
{p10, p2, p4, p5, p7, p8 }
{p1, p2, p10, p5, p7, p8 }
{p9, p2, p4, p5, p7, p8 }
{p1, p2, p9, p5, p7, p8 }
{p10, p2, p9, p5, p7, p8 }
So what is the formula??
