input: Write a python function to classify a list of numbers as 'positive', 'negative', or 'neutral' based on the given criteria.
  assert predict([1, -2, 3]) == 'positive'
  assert predict([-1, -2, 3]) == 'negative'
  assert predict([-1, 1, 3]) == 'positive'
  assert predict([-1, 1, -3]) == 'neutral'
output: def predict(numbers):
      positive_count = sum(1 for num in numbers if num > 0)
      negative_count = sum(1 for num in numbers if num < 0)
      
      if positive_count > negative_count:
          return 'positive'
      elif negative_count > positive_count:
          return 'negative'
      else:
          return 'neutral'
