Hi,
if E(x)=11/3 find the values of a and b
Two unknowns, needs 2 EQs... to find a and b
I.  {{{1/15 + a + 1/5 + b + 1/3 = 1}}} or {{{a+b = 6/15 = 2/5}}}
II. comes from the E(x) = {{{11/3 = 1*(1/15) + 2*a + 3*(1/5) + 4*b + 5*(1/3)}}} or {{{2a + 4b = 4/3}}}
 a +  b = 2/5
2a + 4b = 4/3     |Verify the 2 Eqs and Solve for a and b
