If X is a r. v. with c. d. f. F(x) and its probability distribution is given by then, F (1 5)- F (-0 5)=

Options

  1. A0 2
  2. B0 3
  3. C0 1
  4. D0 4

Correct answer

D. 0 4

Step-by-step solution

(B) array l F(1.5)-F(-0.5) =P[X 1.5]-P[X -0.5] =[P(X=-1.5)+P(X=-0.5)+P(X=0.5)+P(X=1.5)]-[P(X=-1.5)+P(X=-0.5)] =P(X=0.5)+P(X=1.5)=0.15+0.25=0.4 array
