Answer:

Correct Answer: C

Solution:

  •         Probability of the card being a spade or an ace                                                                             $ =\frac{16}{52}=\frac{4}{13} $  . Hence odds in favour is  $ 4:9. $  So the odds against his winning is                                                                                                 $ 9:4 $  .
