MCQ
Statement A (Assertion): In a single throw of a die. The probability of getting a number less than 7 is 1 .
Statement R (Reason) : The probability of a certain event is 1 .
  • ✓
    Both assertion (A) and reason ( $R$ ) are true and reason (R) is the correct explanation of assertion (A).
  • B
    Both assertion (A) and reason ( $R$ ) are true and reason $(R)$ is not the correct explanation of assertion (A).
  • C
    Assertion $(A)$ is true but reason $(R)$ is false.
  • D
    Assertion (A) is false but reason $(R)$ is true.
✓

Answer

Correct option: A.
Both assertion (A) and reason ( $R$ ) are true and reason (R) is the correct explanation of assertion (A).
(a):Clearly, Reason is true.
Now, in a single throw of a die, all the possible outcomes are $(1,2,3,4,5,6)$.
Since, all the numbers are less than 7 , then it is a sure event.
$\therefore \quad$ The probability of getting a number less than 7 is 1 . So, Assertion and Reason both are true and Reason is the correct explanation of Assertion.
