Random is not random?

https://flowlab.io/game/view/819218
go into edit and go into the behaviors for the “check” object.
theres a random test and counter for the numbers 1 2 3.
press play. try testing multiple times.
for some reason, the number 2 is always chosen way more often than 1 and 3.
can someone explain please?

It’s (pseudo) random - so over time it should generate the same number of 1,2, and 3 in your example.
