Why is it 4 balls and 3 strikes?

Excuse me, could you please clarify why the baseball game's rules specify that a batter is out after four balls and three strikes? I understand that these rules have been in place for quite some time, but I'm curious about the historical context and reasoning behind this particular combination. Does it have anything to do with the game's evolution or was it simply a decision made by the rule-makers at some point? It seems like a fascinating aspect of the sport that I'd love to learn more about.
