Answer:
Step-by-step explanation:
The equation for C is: .
C is used to find the coefficient in a binomial expansion.
Another way to look at this is that the formula finds the coefficient in the Pascal triangle that corresponds to the row at the third power. Just a faster way than writing out the Pascal triangle all the time.
This one goes like this:
The 6 and the 3*2 cancel out to give us:
Which is 35.
