There are 600 students in the post-graduate department of a university, and the probability for any student to need a copy of a particular textbook from the university on any day is 0.05. How many copies of the book should be kept in the university library so that the probability may be greater than 0.90 that none of the students needing a copy from the library has to come back disappointed. (Use normal approximation to the binomial probability law.)
