The probability of 2-4-6-8-10 appearing is actually lower than say 1-2-5-6-7.  Look closely at the number of odd and even numbers.

Forget for a minute that 5 numbers are drawn.  Consider drawing just one number.  At first, the odds of drawing an odd or even are nearly equal with a slight advantage towards odd since there is one extra odd number.  

  Odds/Probability of Drawing One Number
  Odd: 1 in 1.96 or 50.9%
  Even: 1 in 2.03 or 49.1%
