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?
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.
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.
