CBSE Class 10 Mathematics (Basic) — Probability

18. A die is thrown once. Probability of getting a number other than 3 is : (a) $\frac{1}{6}$ (b) $\frac{3}{6}$ (c) $\frac{5}{6}$ (d) 1

19. Assertion (A) : The probability that a leap year has 53 Mondays is $\frac{2}{7}$. Reason (R) : The probability that a non-leap year has 53 Mondays is $\frac{5}{7}$. (a) Both, Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A). (b) Both, Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A). (c) Assertion (A) is true, but Reason (R) is false. (d) Assertion (A) is false, but Reason (R) is true.
