Probability of Class 12

Binomial Distribution for Successive Events

If a random experiment is being repeated n times independently and success of an event in this experiment is p, then probability of getting exactly r success out of n trials = Binomial Distribution for Successive Events (where q is the probability of failure of that event, so p + q = 1).

Probability of getting at least one success = nC1pqn - 1 + nC2p2qn - 2 + … + nCnpn = 1 − nC0p0qn = 1 − qn
