Don randomly draws two cards from a standard deck of 52 cards. He does not replace the first card. What is the probability that both cards are aces?

@DaBest21

OpenStudy (jack_prism):

4/52

OpenStudy (anonymous):

at first 4/52 cards are aces then he takes and doesn't replace one so 3/51 now what is 3*4 @thisotherliz

OpenStudy (jack_prism):

there are only 4 aces in a deck and da best would be right, sorry my mistake

OpenStudy (anonymous):

12

OpenStudy (anonymous):

now do 52*51

OpenStudy (anonymous):

2652

OpenStudy (anonymous):

yes so 12/2652 which simplifies to 1/221

for further problems know that if it doesn't say he/she replaced whatever item was took out then make it into fractions with the total going down each time its like if u had 5 cookies and u ate 1 u wouldn't still have 5 u would have 4 so that would at first be 5/5 (because they are all cookies) then for the second cookie its 4/4 if it says it was replaced just don't change the total amount Plz ask me for more help but also read all of this @thisotherliz
