Number of ways, not probability :lookround:

kk..
Hi,
Want to practice 15-20 CAT type RC passages. Any suggestions?
@hanushanand said:?? Kaise? Din't get you! How are you approaching it??
For example, bww ke liye.. 32 black squares to choose from, then you can't choose the 8 white squares that lie in the same row or column as the black one, so 24 white squares left, then I can't choose 6 white squares so 18, but the two white squares are interchangeable so divided by two. 32*24*18/2=6912
@naga25french said:@ankita14 your answer looks good to me .. forgot to divide by 2
It is good, but it doesn't come if you choose the two white squares first. It comes to 6400. Where am I going wrong there.

and BWW me same.. 32*24*18/2 .. Don't know where I am getting it wrong! Verify!
