Create the array.  Use quotient remainder to divide by 2.  Now you have an array where all the odd numbers are now 1, and all the even numbers are now 0.  Sum the array and you have the total number of odd numbers.  The number of evens will be the length of the array divided by the # of odds.

"The number of evens will be the length of the array divided by the # of odds."......you mean subtracted not divided?

Yes.  I think I had divided still on my mind from talking about the Q&R function.

Why are you excluding zero?  It is an even number also.

The original problem deals with random number is the range of 0 to 20, thus zero should not be excluded. If zero should not occur, the random generator needs to be changed to generate numbers from 1..20.

i revised my last post to include the # of zero's...

As has been said, zero is an even number, so I would suggest not to escalate the issues by adding complications that are not requested.

Here's all that's needed. (I included the random generator, because many users take shortcuts that give lower probabilities for the first and last element.)
