A random variable X has the following probability distribution:(a) Find k(b) Find P(0 < X < 4)(c) Obtain cumulative distribution function (c.d.f) of X.

Answer»

(a) K + 3K + 5K + 7K + 9K + 11K + 13K = 1

∴ 49K = 1

∴ K = 491​

(b)  P(0 < x < 4) = P(1) + P(2) + P(3)

493 ​+ 4910 ​+ 4921 ​= 4934​

(c) C.D.F = (2x + 1)K, 0 ≤ x
