Consider the experiment of selecting a card from an ordinary deck of 52 playing cards and determine the probability of the stated event. A face card or a 5 is drawn.
So there are 12 face cards. Plus 5. So that is 13 options out of 52?
aren't there four fives?
There are 12 face cards plus four cards with a "5" on them for a total of 16 cards out of 52. So you end up with 16 chances of 52 that you will draw a face card or a card with a five on it, or 16/52 chance. You should reduce the answer to a 4/13 chance.
I was wondering about that. Thank you both.
