As in Exercise 36 from Chapter 3, there are n voters in an upcoming election in a certain country, where n is a large, even number. There are two candidates, A and B. Each voter chooses randomly whom to vote for, independently and with equal probabilities (a) Use a Normal approximation (with continuity correction) to get an approximation for the probability of a tie, in terms of Φ. (b) Use a first-order Taylor expansion (linear approximation) to the approximation from Part (a) to show that the probability of a tie is approximately 1/Ven, where c is a constant (which you should specify).
