Discrete probability distribution for the probability of number of successes in n independent random trials under the identical conditions. Confidence level

Combinations (number of combinations of n objects taken r at a time) Combinations (number of combinations of n objects taken r at a time) Covariance between X & Y

a = y bx , for line y = a + bx

b = (x x)( y y) for line y = a + bx 2 ( x x)

If X follows B (n, p) then,
