Answer:

nCr = n! / (r!(n-r)!),

Step-by-step explanation:

The formula for C(n,r), also known as "n choose r" or a combination,

is: 

nCr = n! / (r!(n-r)!),

where n is the total number of options and r is number you must choose

The number generated is the total number of possible combinations. 

The ! means factorial. For example, 4! = 4 x 3 x 2 x 1

Hey there! I'm happy to help!

We see that 500 languages is a certain percent of the 7,111 total languages. When working with percent equations, the word "is" means "equals", and "of" usually means "multiplied by" This means that 500 is equal to a certain percent multiplied by 7,111. We can use p to represent this certain percent and create an equation below.

500=7,111p

Let's flip the equation around so the p is on the left side. Variables are usually supposed to be on the left.

7,111p=500

We divide both sides by 7,111.

p=0.0703

As a percent, this is about 7.03%. Therefore, about 7.03% of the total languages spoken globally are represented on WikiTongues.

I hope that this helps! Have a wonderful day! :D
