simple logic if you want that all 3 black are taken out in rth draw , then it's means in last draw you should take out black ball , it means till r-1th draw , you should take 2 black and remaining will be white balls. Now in rth draw u will be left with 1 black and check how many are left for sample space in last draw, if you are not comfortable with r then take some specific example with r as some value then u will be able to understand concept.
