    but in normal distribution if the sum has given us the probability value and we need to find the x value or the z value is there any way to do that or do we have to use normal tables

    Nice overview. While this calculator seems well rounded with many abilities, my biggest complaint is the choice of the case color and use of small colored key labels (above the keys). For us shade-blind folks, it can be very difficult to read the labels... especially the red and blue ones. The faux carbon fiber finish also contributes to making them hard to read under reflected light. A better choice for the case would have been white. It is still mostly usable and at only a cost of $15, I'll probably keep mine... but will be looking for another that is much easier to read.
