Answer :
The key point to solve the problem:
If a probability distribution is given then as per its definition, Sum of probabilities associated with each value of a random variable of given distribution is equal to 1
i.e. ∑(pi) = 1
Given distribution is :
(i)
∴
∴ (i)
(ii) P(X>2) = P(X = 3) =
∴ P(X>2) =
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2) = =
…(ii)
(iii) ∴ P(X>2) + P(X≤ 2) =
