Var(y) = 3F(Q1)+F(Q2)-[F(Q1)+F(Q2)]^2
using N distribution table (Z-score),where F(x),representing the reqrd function.
Again we have
F(Q1) = 0.25 for x = -0.67
F(Q2)= 0.50... (view)

The distribution of variable x is Normal with mean = 0 and sd =1; y is such that
for y=1 ; x<= Q1,
for y=2 ; Q1<= x<=Q2,
and for y=3 ; Q2<= x ,
then find the variance of y... (view)
