What are the chances to spawn 4 baby horses in a row in Minecraft?

so this is just something I was wondering. I was trying out my texture pack, and when I was trying to spawn in horses, I spawned in 4 baby horses in a row. What are the chances of this?

Here is what I searched, and found no results.

Solution 1:

According to the Minecraft Wiki, the chance of spawning a baby horse is 20%.

Calculating the chance of that occurring 4 times in a row:

0.2 * 0.2 * 0.2 * 0.2 = 0.0016 = 0.16%

As you can see, that's very unlikely.

However, there is another mechanic in Minecraft: When you use the Spawn Egg on a mob (in your case, the horse), you will always spawn a baby mob. This would raise your chance back up to 20%. So not that unlikely.
