Why wouldn't this be C?

(187/350) * (247/350)

Does that only work for separate events?

I think it should be C.

The condition would be that the randomly selected student should be female and also a postgraduate, so this can be calculated as:

P( Female)= (247/350)

Try grid method. Nothing about male to female ratio in postgraduate or graduate column can be ascertained.
