Binomial experiment:

\

A binomial experiment is a probability experiment that satisfies the following conditiions.

\

(a) The experiment is represented for a fixed number of independent trails $\"\"$ .

\

(b) Each trail has only two possible outcomes, success $\"\"$ or failure $\"\"$ .

\

(c) The probability of success $\"\"$ or $\"\"$ is the same in every trail.The probability of failure is $\"\"$ .

\

(d) The random variable $\"\"$ represents the number of successes in $\"\"$ trails.

\

\

Observe the experiment:

\

It is binomial experiment.

\

The numer of times toss a coin is $\"\"$ .

\

$\"\"$ each toss.

\

$\"\"$ .

\

Either tail or head.
