A random variable has the following probability distribution The then value of p is

Options

  1. A1 10
  2. B1 30
  3. C1 100
  4. D3 20

Correct answer

A. 1 10

Step-by-step solution

array ll & Here, & 0+2 p+2 p+3 p+p^2+2 p^2+7 p^2+2 p=1 & 9 p+10 p^2=1 & 10 p^2+9 p-1=0 & 10 p^2+10 p-p-1=0 & 10 p(p+1)-1(p+1)=0 & p= 1 10 or p=-1 & But 0 p 1 & p= 1 10 array
