If the probability distribution of a random variable X is as follows, then k = array |c|c|c|c|c| X = x & 1 & 2 & 3 & 4 P ( X = x ) & 2 k & 4 k & 3 k & k array

Options

  1. A1 10
  2. B2 10
  3. C3 10
  4. D4 10

Correct answer

A. 1 10

Step-by-step solution

We know that aligned & P_i=1 2 k+4 k+3 k+k=1 & 10 k=1 k= 1 10 aligned
