Hi,
I have a problem understanding Indistinguishable events in the flashcards on pg. 55. Could you please explain what you mean by "divide the factorial of the items in the set by the product of the factorials
of the number of indistinguishable elements." Thanks.

Hi Eric,
Is it enough if I practise for GMAT only from OG 12 or shall I buy some more refernce books?
I also have OG 10. Should I practise separately from both OG 10 and OG 12 or OG 12 is sufficient?
