A deck of cards has 5 pink, 2 gray, and 6 black cards. You pick 2 cards from the deck without replacement. What is the probability that the first card is gray and the second card is pink?
+865 I'm not sure this is correct, please check for me.
P( the first card is gray) = 2 / (5+2+6) = 2/13.
P (the second card is pink) = 5/ (5+2+5) = 5/12
P (the first card is gray and second is pink) = (5/12)(2/13) = 10/156.
Simplified = 5/78.
Please check for me.

+865 Do you mean like being more confident?
I dunno, it's kind of a habit of not being confident enough.
If you mean actually giving points to myself, i don't know how to do that.
