Asked by Lucy
Two cards are drawn from a standard deck of 52 cards. What is the probability of drawing 2 queens or 2 red cards?
(4/52)(3/51)=1/221 ---drawing a queen
(26/52)(25/51)=25/102--drawing a red card
(1/221)(25/102)= 25/22542 drawing a queen or red card
Is this correct??
Thanks for your help

No. You need to find the OR probability, a little tricker. And remember two queens are red...
I cant do it better than this. Study it.
