In a 2-way frequency table, you take the row entry and divide it by its row total to get a decimal.
For your example:
It starts out like this:
sunny snowy
Male: 17 11
Female: 15 16
Add the rows up.
sunny snowy total
Male: 17 11 28
Female: 15 16 31
Then divide the number the by the total:
sunny snowy total
Male: 17/28 11/28 28
Female: 15/31 16/31 31
Yours says to round to the 1000th place, so it ends up like:
sunny snowy
Male: .607 .393
Female: .484 .515
Hope that helps!!
