Let X ~ Bin(n, p). Show that if x is an integer between 1 and n inclusive, then a. P(X = x) P(X = x- 1) (2+1)() - x + b. Show that if X - Bin(n, p), the most probable value for X is the greatest integer less than or equal to np + p. [Hint: Use part (a) to show that P(X = x) 2 P(X = x - 1) if and only if x < np + p.]
