Probability of a loop

(c) Imagine exccuting the following loop count :=0; for i = l to 106 do c RANDOM(f1,. ,10)/choosing c at random from, 1 iffon 8191 then count := count +1; end if 61 * end for What is the probability that count is nonzero when the loop terminates? (d) What is the value of 1 - 1/e
