What is the probability of drawing a queen from a 52 deck ...

You have 52 different cards with 4 queens in 52 cards but you will take only one card from 52 cards to calculate probability that card is Queen or not ? It permutation P in mathematics , this permutation is nPr here n=52 ,r= 1 so nPr = n!/(n-r)! = 52!/(52u20131)! = 52 means 4/52 = 7.69% . If you take a card out of 52 cards if it is not queen you are to leave that set , then take another different card ,another different card so on then there is 7.6% probability to get a queen out of 52 cards .
