The possible outcomes for a single hatchling are that it is normal, it is underweight, or it is extremely underweight. You have a 12/200, or 6% chance it is extremely underweight (percentage is out of 100, or 12/200 = 6/100 or 6%). You have a 38/200 or 19% chance it is underweight, and you have 150/200 or 75% chance it is normal.
