calculate the probability that it shows up

c) 10 +/- 2 times
d) 10 +/- 5 times
e) 10 +/- 10 times
which range would guarantee a 90 % certainty? 95 % certainty? 99% certainty?
calculations are necessary. but important is the discussion of the results...
can you give me the formula to calculate a) and the one to calculate b c d e..
and how can i calculate the certainty?
can you help me??
thanks for showing me your calculations, thoughts, ideas, explanations, ...
