How many aces and 9's are in the deck. Hint: 4 of each card.

8! =)

rebecca · Answer

8/52 then simplify.

ineedhelplz · Answer

In statistics the word or always means to add and the word and always means to multiply. So it says an ace OR a six. so find the probability of each and add them together. 

4 aces out of 52 cards 
4 sixes out of 52 cards 

so 4/52 + 4/52 = 8/52 

8/52 reduces to 2/13

If something is wrong, just report and let moderators handle it, don't go into things yourself, it never ends well unless both sides are humble.
