Solution of problem N1110 Laplace probability theory

1110. The probability of occurrence of an event in each of the n independent trials is 0.64. Find the number n at which, with a probability of 0.9876, we can expect that the relative frequency of occurrence of the event deviates from its probability by an absolute value by no more than 0.02.
