Solution

The correct option is B 1213
For choosing a queen card from a well-suffled deck of 52 playing cards,

total number of outcomes= number of cards in the deck= 52
number of favorable outcomes= number of queen cards in the deck= 4

P(choosing queen)=Number of favorable outcomesTotal number of outcomes

P(choosing queen)=Number of queens in the deckTotal number of cards in the deck

P(choosing queen)=452=4×14×13=113

We know,
P(not choosing queen)=1P(choosing queen)

P(not choosing queen)=1113

P(not choosing queen)=1313113=13113=1213

The probability of NOT choosing queen from a well-suffled deck of 52 cards is 1213.
