Sam writes down the numbers 1, 2, 3, ..., 99

 

(a) How many digits did Sam write, in total?

(b) Sam chooses one of the digits written down, at random.  What is the probability that Sam chooses a 0?

(c) What is the sum of all the digits that Sam wrote down?

sam wrote 99 digits,
the probability is 0, as he didn't write it...
the sum is 4950
Hope This Helps!
