Just go my HP 20B, and the Math Probabilities are there; but the manual does not tell how to obtain results. I have tried many ways. Does anyone out there know how to utilize these functions yet? HP needs to release an advanced user manual for this powerful inexpensive machine. If they did so, every college student would absolutely need one.
