Short Answer

Expert verified

Binomial distribution, i.e., $f (x) = C (50, x) {(\frac{4}{5})}^{x} {(\frac{1}{5})}^{50 - x}$ .

The graph is shown below

Step by step solution

Given Information.

$\begin{array}{rcl} n & = & 50 \\ p & = & (\frac{4}{5}) \\ q & = & (\frac{1}{5}) \end{array}$

Definition of Binomial distribution.

The discrete probability distribution of the number of successes in a sequence of $n$ independent experiments is the binomial distribution with parameters $n$ and $p$ .

Solve binomial distribution for given values.

Binomial distribution is,

$f (x) = C (n, x) p^{x} q^{n - x}$

Substitute values,

$f (x) = C (50, x) {(\frac{4}{5})}^{x} {(\frac{1}{5})}^{50 - x}$

Hence, binomial distribution is $f (x) = C (50, x) {(\frac{4}{5})}^{x} {(\frac{1}{5})}^{50 - x}$ .
