In binomial distribution, the formula to find the mean and variance (respectively) is given by :-
, where n= Total number of trials.
p= probability of getting success in each trial.
Let X be the random variable that is the number of heads in the outcome.
Given : An experiment consists of tossing a coin 6 times.
i.e. n= 6
Also, total outcomes in coin =2 (tail , head)
Probability of getting head in each trial = (Favorable outcome)/ (Total outcome)
Mean =
Variance =
Hence, the mean and variance of X is 3 and 1.5 respectively .
