An estimated 40% of all people were born after the year 2000. If two people are selected at random from around the world, what a
sukhopar [10]

The chances that NEITHER of these two selected people were born after the year 2000 is 0.36

<h3>How to determine the probability?</h3>

The given parameters are:

Year = 2000

Proportion of people born after 2000, p = 40%

Sample size = 2

The chances that NEITHER of these two selected people were born after the year 2000 is calculated as:

P = (1- p)^2

Substitute the known values in the above equation

P = (1 - 40%)^2

Evaluate the exponent

P = 0.36

Hence, the chances that NEITHER of these two selected people were born after the year 2000 is 0.36

What is 6 divided by a number that will give you 12
AURORKA [14]

  ▶︎◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◀︎

Hello There!

We need to find what number, if 6 is divided by it, gives us 12.

This isn't hard, I promise! I am going to take you through a few steps, and we'll find the answer.

Are you ready? Then let's begin...:)

Procedure:

  ✦ We can think about it as: 6 divided by what number gives us 12?

(let the number be z)

^6/_z=12

Multiply both sides by z

6=12z

Divide both sides by z

z=^6/_{12}

Which is the same as

z=^1/_2

  • hope it's helpful!
  • wishing you a great day!

Greetings!
