Question: The function f (x) = kx n (1 - x) m , 0 x 1 where n > 0, m > 0, and

The function f (x) = kxⁿ (1 - x)^m, 0 ≤ x ≤ 1 where n > 0, m > 0, and k is a constant, can be used to represent various probability distributions. If k is chosen such that S f(x) dx = 1 then the probability that x will fall between a and b (0 ≤ a ≤ b ≤ 1) is

The probability that ore samples taken from a region contain between 100a% and 100b% iron is
