That's for 1 hero. If you random 200 times you can expect not to get around 13 heroes.
The probability of randoming Meepo once is 27.06%.
The probability of randoming Meepo more than once is 59.53%. (2, 3, 4, ... times)
The probability of randoming Meepo more than twice is 32.33%. (3, 4, 5, ... times)
The probability of randoming Meepo more than thrice is 14.19%. (4, 5, 6 ... times)
Numbers are from a binomial calculator.
It is normal that you random a couple of heroes multiple times. It is more likely to random a hero over 3 times than not to random him at all when randoming 200 games.
Also I believe all heroes are randomable since I can't think of one hero which hasn't been randomed. My team loves to random.
