Use your LUID number (LABCDEFGH) to define the parameters of this test. For instance, LUID L12345678 A=1, B=2, C=3, D=4, E=5, F=6, G=7, H=8. In the same way A+3 = 1+3 = 4; B+D = 2+4 = 6; EF = 56, GH = 781. If you get a uniformly random [0,1) with value 0.BCDECGHA, compute the value of a uniformly distributed random variable X if the feasible range is from ABC to ABC+DEF.
