CUET Mathematics - The random variable x has a probability distribution p(x) of the form p(x = r) = cases r - k, & if 2 ≤ r ≤ 4, \\ 0, & otherwise, cases where r N 0 and k R^+, where R^+ is the set of natural numbers. Then: (A) k = 1/9 (B) P(2 ≤ x ≤ 3) = 1/2 (C) P(x = 4) = 1/3 (D) P(x > 1) = 7/9 Choose the correct answer from the options given below. | PYQs + Solutions
