As the title suggests, I'd like to learn why traceroute sends three packets per hop by default. (Nothing important, I'm just curious).
Edit: packages != packets

First, they're called "packets", not "packages".
Multiple packets result in more information. Soft failure, asymmetric routing, and other network weirdness can't be seen with a single packet. With 2 packets, which result do you believe? With 3 packets, ...
OTOH, programmer picked a default.

Yes, I realised that after posting the question. Sending more than a single packet is of course also useful for making sure the round trip times are realistic.

Another reason for why traceroute sends three probes by default is to provide more detailed results for round-trip time (RTT) by showing the RTT of each of the three probe.
You can modify the number of probes using the --queries / -q flag
