Assuming the order does not matter, you want the number of combinations of 9 things taken 5 at a time. The combinations can be shown as C(9,5), 9C5.
C(9, 5) =
9/5(9-5) =
9*8*7*6*5 / 5*4
The 5 terms cancel.
9*8*7*6 / 4*3*2 =
9*7*2 =
126
The above change is because 4*2 cancels the 8 in the numerator and 6/3 = 2
Therefore, the solution is 126.

Step-by-step explanation:
We can easily solve this question by using a graphing calculator or any plotting tool.
The equation is
f(x) = (1/4)*(4)^(x)
Which is an exponential function, that grows rapidly to infinity as x increases.
