Probability if getting hit by a ball

[Clemogo5]

If 100 balls are thrown at me and each ball has a 90% probability of hitting me, then what is the probability of no balls hitting me? What is the probability of at least 1 ball hitting me? What is the probability of at least 2 balls hitting me? What is the general formula for calculating the probability of at least x balls hitting me?

I suggest that you tackle a simpler question. Use ten balls not one hundred.
The numbers are much nicer. What is the probability of you being hit by none of the ten.
Now is at least one the complement of none? Please post your answers..
