Which of the following are the properties of Normal Distribution function f(x) and Normal probability curve:
(A) The probability of success remains the same in each trial and the number of trials is small in number.
(B) The curve is bell-shaped and is symmetrical about the mean.
(C) If set of n trials are repeated N times, then frequency f(r) of r successes is given by f(r) = N.p(r) = N, r=0,1,2,...
(D) As x increases numerically, f(x) decreases rapidly and the maximum value of f(x) occurs at x=μ(mean)
