S3 Probability Fair DieWatch this thread
could anyone please help me with this problem.
I end up with p(z < 0.0585sqrt(n)) > 0.995 which, by referring to the tables, implies that 0.0585sqrt(n) >2.6.
The solutionbank, however, gives 0.0585sqrt(n) > 2.5758
2.5758 isn't a value of z which is in the tables, and I can't understand where it comes from.
It makes a huge difference: book gives n => 1936, I get n=> 1976.
I wonder if op appreciates finally getting an answer a decade after their a levels.
