This PS2 must be a hard-working dude!

The map does not make any mistake!

Nah, only 10€. But also the students only had to pay 10€ in total.

In highschool we had a maths teacher who always did the birthday paradox as a kind of opener in the first lesson. https://en.wikipedia.org/wiki/Birthday_problem

He bet 10€, that there are 2 students with the same birthday in the classroom of (abt) 30 students. The class was allowed to work out, if they want to accept the bet, or not (exchanging birthdates was not allowed ofc).

Usually the students think, that it’s nearly impossible, and accept the bet. Little did we know, that the probability of success was around 70% for the teacher.

Make purple yellow and one of the reds purple.
