a river has fallen into the lego in helicopter city quick! build the man

I assume you mean 9C4

9C4! = 0

Anyway,

9C4 = 9!/(5!4!) = 9*8*7*6 / 4*2*3*1 = 126

9P4 = 9!/5! = 9*8*7*6 = 3024

a City has fallen into a man in Helicopter City build the river !

a Man Has Fallen for am Man in Lego City
A Helicopter has fallen into the city in Lego River Quick! build a man
a River has fallen into the man in lego City Quick build a HeliCopter !

A river has citied into a man in Helicopter fallen. Quick! Build the lego!

To simplify 9C4, we need to calculate the value of the binomial coefficient.

The formula for the binomial coefficient is given by:
nCk = n! / (k! * (n-k)!)

Here, n is the total number of items to choose from and k is the number of items to choose.

In this case, n = 9 and k = 4. So, we need to calculate 9C4.

Using the formula, we can calculate it as follows:
9C4 = 9! / (4! * (9-4)!)

To simplify the calculation, we can calculate the factorials first.

9! = 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1
= 362,880

4! = 4 * 3 * 2 * 1
= 24

(9-4)! = 5! = 5 * 4 * 3 * 2 * 1
= 120

Now, we can substitute the factorials back into the formula:

9C4 = 362,880 / (24 * 120)
= 362,880 / 2,880
= 126

Therefore, the simplified value of 9C4 is 126.

So, the correct option from the given choices is A. 126.

thank you!

For 9C4 the answer is 126

Just did the test.
