A random variable X has the following probability distribution Then P (X^3 2 )=

Options

  1. A45 49
  2. B15 49
  3. C1 49
  4. D40 49

Correct answer

A. 45 49

Step-by-step solution

aligned & P(x)=1 & 49 k=1 aligned Now, P (x^3 2 )=1-P(X<2) aligned & =1- P(X=0)+P(x=1) & =1- 1 49 + 3 49 & = 45 49 aligned
