Bernoulli’s Distribution

Bernoulli’s Distribution

It is discovered by a Swiss Mathematician James Bernoulli (1654-1705) for a trial which has only two outcomes viz. a success with probability p and a failure with probability q= 1 – p.

Characteristics of Bernoulli Distribution

i. Number of trials is one

ii. q = 1 – p

iii. Constants of the distributions

iv. (i) mean = p (ii) variance = pq (iii) standard deviation = √pq
