 Hi everyone,
 After I changed the code as Paul's note above the code started to 
create identical results for both bet_rand and bet_red.
 Thanks to everyone who helped. Its much appreciated.
 The new code reads as this:


colors = {}
[2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, 
35].each do |i|
  colors[i] = :black
end
[1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36].each 
do |i|
  colors[i] = :red
end
  colors[0] = :zero

bet_rand = 0
bet_red = 0

puts 'How many rolls to simulate'
number_of_rolls = gets.chomp.to_i

number_of_rolls.times do

  number_01 = rand(37)
  color_01 = colors[number_01]
  number_02 = rand(37)
  if number_02 == [:red, :black]
    color_02 = colors[number_02]
    else
    color_02 = :red
  end

  if color_01 == :red
    bet_red += 1
  else
    bet_red -= 1
  end

  if color_02 == color_01
    bet_rand += 1
  else
    bet_rand -= 1
  end
end

puts bet_rand
puts bet_red
