Sami how does one do that

@Ammarah Sami,

Do you want to do this mathematically or actually create a random number generator and simulate it?

Eng what does Amm mean by his last phrase

(Her?) Apparently this her first with no profile yet. Yet I seem to be the only participant at all interested in others'. Why is that

@dalehileman,

What I think (s)he is asking is what is the expected distribution for the number of heads out of ten flips if you conduct forty trials. The probability of any given number of heads is

10! / n! / (10-n)! / 2^10

So the result table where "Count" is out of forty trials would look like:

Code:

N	   Prob	Count

0	   0.1%	   0

1	   1.0%	   0

2	   4.4%	   2

3	   11.7%   5

4	   20.5%   8

5	   24.6%  10

6	   20.5%   8

7	   11.7%   5

8	   4.4%	   2

9	   1.0%	   0

10	   0.1%	   0

But I'm not exactly sure that is what is being asked.

Me nuther Eng but thanks for the ed. guess

Even more helpful to the Average Clod (me) might be a def of N and Count

Tho we probly do know what prob means

@dalehileman,

N in my table is the number of heads after flipping ten coins. If you get ten tails, then N is zero, ten heads would be an N of 10. Count in this case is just the probability times 40 since the OP wanted to do this 40 times.

@engineer,

I interpret it the same way you do.

@dalehileman,

I took a course in Statistics in college, but that was two lifetimes ago. I was impressed with differential calculus and how it can be used, but have forgotten it all.

I've forgotten virtually everything, even lately. A few years ago I wrote a book entitled "The World, as Told to the Young Man, in short words," 77,000 words of one syllable each. Don't remember anything but the title
