Let's go with integers.

I cannot disprove this statement with code from a range of numbers up to 5.
According to retina's rules from the above quote, his statement is correct when the range is set to an odd number!

Code:
evens = [x for x in range(5) if x % 2 == 0]
print(evens)
for number in evens:
evens.append(number / 2)
print(evens)
break
odds = [x for x in range(5) if x % 2 != 0]
print(odds)
for number in odds:
odds.append(number * 2)
print(odds)
break

Therefore there are more even numbers than odd numbers. True because Even+even= odd Odd+odd = odd Only Even +odd = even

I can totally understand this theory from the counting of base 5, 7 and 9. Any odd based counting will result in more even numbers.

Haha, for some reason I can't stop laughing. Paraphrasing a famous person, "I know I am stupid, but when I look around, I get wings".

An even number multiplied by an odd number produces an even number. An even number multiplied by an even number produces an even number. So there are more possible even number results. Therefore there are more even numbers than odd numbers.

Which makes not only one, but ALL his "equations" wrong. As wrong they are, they "prove" the contrary to your affirmation. But if they should have been right, witn "addition", they still prove your point. Lord's ways are complicate... That's why I couldn't stop laughing. Last fiddled with by LaurV on 2020-10-15 at 09:41

Nope. Number base does not matter at all. 9 = 14 base 5 =12 base 7 = 10 base 9 =11 octal = 1001 binary is odd. They are merely representations of a count or value.

ooooooooo groups into pairs with one left over, a definition of odd.
oo oo oo oo o

Odd bases will however result in somewhat more rightmost even digits than odd rightmost digits, in randomly or uniformly distributed values.
