Probability 1 mark Medium

In an experiment of throwing a die, Assertion (A): Event

E_{1}

: getting a number less than

3

and Event

E_{2}

: getting a number greater than

3

are complementary events. Reason (R): If two events

E

and

F

are complementary events, then

P (E) + P (F) = 1

Assertion (A): In an experiment of throwing a die, Event $E_{1}$ : getting a number less than $3$ and Event $E_{2}$ : getting a number greater than $3$ are complementary events.

Reason (R): If two events $E$ and $F$ are complementary events, then $P (E) + P (F) = 1$ .

(a)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, but 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

(d) Assertion (A) is false, but Reason (R) is true.
