Options:

A) $ \frac{4}{6} $

B) $ \frac{1}{9} $

C) $ \frac{1}{36} $

D) None of these

Show Answer

Answer:

Correct Answer: B

Solution:

  • [b] Total number of outcomes $ n,(S)=6^{2}=36 $ and event of getting a total score of 5 = {(1, 4), (2, 3), (3, 2) (4, 1)} Favourable outcomes n[e] = 4
    $ \therefore $ Required probability $ =\frac{n(E)}{n(S)}=\frac{4}{36}=\frac{1}{9} $
