a random variable
x -2 -1 0 1
p(x) 1/8 1/8 1/4 1/2
find probablity distribution function of
1) U=3x+5
2)W=x^3+3
3)draw the graph of commutative distributive function U and W
kvnmurty:
is it commutative distribution or C umulative distribution functoion??

u = 3 x + 5 . x = -2 with probablity 1/8. So u = 3*-2 +5 = -1 with probability = 1/8
See enclosed documents
p(x) = p(u) =p(w) 1/8 1/8 1/4 1/2
probability summing 1/8 1/4 1/2 1
value of x -2 -1 0 1
value of u -1 2 5 8
value of W -5 2 3 4
c umulative probbility is prob ( x < a value) = summation of probabilities for all smaller values
