I think I have got the necessary formula in a spreadsheet now so if you could indulge me (just one more time hopefully!! ) ,I have tried some random numbers in it:-
If there are 30 people in the class and the set is a b c d e f what is the probability that 4 pupils read set a b e and f?
My spreadsheet says 9%
Is this right?
