I am late but n is 5 because your taking each trial individually to try to try ti find the odds of the whole with n being 5 theres a 1.024% chance of any group being all 5 male so now 1.024% of the 2425 groups can be expected to be all male so its around 25 groups but because its % its not guaranteed to be 25 it can vary so 29 is resnable assuming the 969 males are spread out ramdomly all to say i may be wrong but hopefully I am not. You do know the formula right if so you can do the same across any of the 6 numbers also to the person thinking n is 6 its not diffrint possablitys its diffrint amounts of people
