Answer:

The correct answer is C. 42.2%

Explanation:

Total number of cards in the deck of playing cards = 52

Number of spades in the deck of playing cards = 13

Number of cards other than spade = 52 - 13

= 39

If she draws a card 3 times and doesn't get a spade, she loses.

So, She loses only if he gets all the three cards other than spade


\text{Probability that she does not get a spade in first draw = }(39)/(52)

Now, The card is replaced if she does not get a spade.


\text{So, Probability that she does not get a spade in second draw = }(39)/(52)


\text{Similarly, Probability that she does not get a spade in third draw = }(39)/(52)


\text{Thus, Probability that she will lose the game = }(39^3)/(52^3)=0.422


\text{Also, The percentage of Probability that she will lose the game = }0.422* 100=42.2\%

Hence, The correct answer is C. 42.2%
