First, the Poisson Distribution describes events which have a small probability of occurrence at any very precise single value, like 3.546732190, but which nonetheless occur very very frequently in a range of values. Also the mean or average or expected value are the same as the variance, in your case, three (I think you meant three). So looking up the tables for this (or plugging it in Excel) the prob x=4 exactly is 0.1680

This is your permutations key. Press 11 then second function button and then RCL button. Finally press 0 and equals.

The square root is the second function of the "3" key. To calculate the square root of 2, press 2 2ndF =

To calculate this you press ALPHA (the green key) and 5 or 6 depending on if you want sample variance (ALPHA 5) and for population variance (ALPHA 6).

push 2nd F and the divide key. You will see % written above the key in orange

There is a BGN/END key (2nd F) (FV)

It's marked "y-superscript-x" and is the shifted function of the DEPR key.

You may download a copy of the manual here.

Press SETUP 0 0 then select the desired number of digits after the decimal point. See pages 8 and 9 of the manual at http://files.sharpusa.com/Downloads/ForHome/HomeOffice/Calculators/Manuals/cal_man_EL738.pdf

I don't know about this specific calculator, but there is probably a button on your calculator that has a "y" with an "x" as a superscript (exponent). Or is could be reversed. But you wanted 2^8, you would push the 2 first, then the exponent button, then the 8, and there's your answer.

Good luck.

Check the understanding of the problem you are dealing with. The result is much too be for any practical application. result is greater than 10^500.

If you are talking about the multiplication sign, look for a key marked with a cross. It should be in the same column as the other operations, between the subtraction (-) and the division keys.

Almost exactly the way you wrote it. Press1 . 3 2ndF y^x 1 / 3 - 1 =Of course, that calculates 1.3/3 - 1. If you really mean the cube root of 1/3 then subtract 1, press1 . 3 2ndF y^x ( 1 / 3 ) - 1y^x is the shifted function of the DEPR key.

Use the y^x function (2ndF DEPR). For example, to calculate 2 to the 3 power, press 2 2ndF DEPR 3 = .

The EL-738 doesn't have a fraction mode like some other Sharp calculators.
