A regular six-sided die is rolled 1000 times. Use the binomial distribution to determine the standard deviation for the number o

ANTONII [103]

The standard deviation for the number of times an odd number is rolled is 15.8

<h3>How to determine the standard deviation?</h3>

The given parameters are:

Die = regular six-sided die

n = 1000

The probability of rolling an odd number is:

p = 1/2 = 0.5

The standard deviation is then calculated as;

$\sigma = \sqrt{np(1 - p)$

This gives

$\sigma = \sqrt{1000 * 0.5 * (1 - 0.5)$

Evaluate the products

$\sigma = \sqrt{250$

Evaluate the root

$\sigma = 15.8$

Hence, the standard deviation is 15.8

What is 1/5 × -3/2 +4/5 × -2/7 × -1/6 × -2/7

velikii [3]

Answer:

$\frac{-457}{1470}$

Step-by-step explanation:

$\frac{1}{5} \times \frac{-3}{2} + \frac{4}{5} \times \frac{-2}{7} \times \frac{-1}{6} \times \frac{-2}{7}$

$(\frac{1}{5} \times \frac{-3}{2}) + (\frac{4}{5} \times \frac{-2}{7} \times \frac{-1}{6} \times \frac{-2}{7})$

$\frac{-3}{10} +\frac{-16}{1470}$

$=\frac{-457}{1470}$
