10th Class Mathematics Probability Question Bank MCQs - Probability

If two dice are thrown once, then the probability of getting a total more than 9 is:

A) \[\frac{5}{6}\]

B) \[\frac{1}{6}\]

C) \[\frac{1}{3}\]

D) None of these

Correct Answer: B

Solution :

[b] Total no. of sample outcomes \[=6\times 6=36\]

Favourable outcomes

\[\{(4,6),(5,5),(5,6),(6,4),(6,5),(6,6)\}\]

\[\therefore \] Total no. of favourable outcomes =3

So. required probability \[=\frac{6}{36}=\frac{1}{6}.\]
