Suppose that X is a random variable that has a binomial uncertainty distribution with parameters n = 10 and π = 0.4. Calculate t
swat32

The numerical values of the mean and standard deviation are 4 and 1.55, respectively

<h3>The numerical value of the probability that x = 6. </h3>

The given parameters are:

n = 10

π = 0.4

The probability is then calculated as:

P(x) = ^nC_x * \pi^x *(1-\pi)^{n-x}

So, we have:

P(6) = ^{10}C_6 * 0.4^6 *(1-0.4)^4

Apply the combination formula

P(6) = \frac{10!}{6!4!} * 0.4^6 *0.6^4

So, we have:

P(6) = 210 * 0.4^6 *0.6^4

Evaluate

P(6) = 0.1115

Hence, the numerical value of the probability that x = 6 is 0.1115

<h3>The numerical values of the mean and standard deviation </h3>

The mean value is:

\bar x = n\pi

This gives

\bar x = 10 * 0.4

\bar x = 4

The standard deviation value is:

\sigma = \sqrt{\bar x(1-\pi)

This gives

\sigma = \sqrt{4(1-0.4)

\sigma = 1.55

Hence, the numerical values of the mean and standard deviation are 4 and 1.55, respectively
