Case 1, b = n/2: In this case, from equation 2, the whole sample space is covered so pe = 1.
Also F(x) = F¯(x) > 1/2 so pc = 1. Because the unique peak of the f(x) function
happens at n/2 when n is even (n must be even when b = n/2), we can see that pm = 1.
Also because of that peak, min n
F(x), F¯(x)
o
is maximized at b = n/2 and pb = 1.
