The formula C(n, r) calculates the total number of ways of picking r objects out of n.
The formula works as follows:

where n! is 1*2*3*...*(n-1)*n
So, we calculate C(150, 4), which will give us the total number of ways we can make the selection of the computers.


many ways.

Answer: A. _3x2x2____
7x2x2
Step-by-step explanation:
given fraction 12/28
here is the numerator = 12 = 2x2x3
here is the Denominator = 28 = 2x2x7
the prime factorization simplest form is _12_= _2x2x3______
28 7x2x2
the simplest form is 12/28 is 3/7
