I feel like an idiot here but I have a question about this
The formulas for a sampling distribution of a sample proportion are being used. This is because the population proportion from which the sampling proportion is taken from is impossible to account for (since there is an infinite number of hands that are posible).
i.e. We use s.d. = sqrt( p(1-p)/n )
and not s.d. = sqrt( np(1-p) )
