Binomial distribution arises, when we perform an experiment
number of times.
Each conduct is called a trial.
A trial results in success or failure.
The probability of getting a success remains constant
irrespective of the trial(p).
Trials are independent.
Then the probability of getting r successes in n trials is nCr pr(1-p)n-r
Probability of getting 3 heads in 5 tosses = 5C3 (1/2)3 (1/2)2
= 5C3 (1/2)5 =10* 1/32 =5/16
