If you toss 100 fair coins (chance is 50% that it is heads)
What is the chance that you will get 60 or more heads.

Does anyone know how to calculate this probability?

Hmm, could you explain a bit more. I know how to calculate the chance of exactly 60 heads but how do you calculate the chance of 60 or more? So the chance of exactly 60 plus the chance of exactly 61 plus the chance of exactly 62 etc.

This could really help me.
