19.9 A small opinion poll. Suppose that 80% of a university’s students favor increasing the number of police patrolling campus at night. You ask 10 students chosen at random. What is the probability that all 10 favor increasing the number of police patrolling campus at night?

  1. (a) Give a probability model for asking 10 students independently of each other.

  2. (b) Assign digits to represent the answers Yes and No.

  3. (c) Simulate 25 repetitions, starting at line 129 of Table A. What is your estimate of the probability?
