Solved Example: :
what is 52 choose 5?
step 1 Address the input parameters and observe what to be found:
Input values:
Total number of distinct elements (n) = 52
The number of elements drawn at a time (k) = 5
What to be found:
Find the total number of possible combinations while choosing 5 elements at a time from 52 distinct elements without considering the order of elements.
step 2 Find the factorial of 52:
52! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12 x 13 x 14 x 15 x 16 x 17 x 18 x 19 x 20 x 21 x 22 x 23 x 24 x 25 x 26 x 27 x 28 x 29 x 30 x 31 x 32 x 33 x 34 x 35 x 36 x 37 x 38 x 39 x 40 x 41 x 42 x 43 x 44 x 45 x 46 x 47 x 48 x 49 x 50 x 51 x 52
step 3 Find the factorial of 5:
5! = 1 x 2 x 3 x 4 x 5
step 4 Find the factorial of difference between 52 and 5:
(52 - 5)! = 47!
47! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12 x 13 x 14 x 15 x 16 x 17 x 18 x 19 x 20 x 21 x 22 x 23 x 24 x 25 x 26 x 27 x 28 x 29 x 30 x 31 x 32 x 33 x 34 x 35 x 36 x 37 x 38 x 39 x 40 x 41 x 42 x 43 x 44 x 45 x 46 x 47
step 5 Apply the values of 52!, 5! and 47! in the nCk formula:
nCk = n!/k! (n - k)!
52C5 =52!/5! x 47!
=1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12 x 13 x 14 x 15 x 16 x 17 x 18 x 19 x 20 x 21 x 22 x 23 x 24 x 25 x 26 x 27 x 28 x 29 x 30 x 31 x 32 x 33 x 34 x 35 x 36 x 37 x 38 x 39 x 40 x 41 x 42 x 43 x 44 x 45 x 46 x 47 x 48 x 49 x 50 x 51 x 52/(1 x 2 x 3 x 4 x 5) x (1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12 x 13 x 14 x 15 x 16 x 17 x 18 x 19 x 20 x 21 x 22 x 23 x 24 x 25 x 26 x 27 x 28 x 29 x 30 x 31 x 32 x 33 x 34 x 35 x 36 x 37 x 38 x 39 x 40 x 41 x 42 x 43 x 44 x 45 x 46 x 47)
step 6 Simplify the above 52C5 equation:
=1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12 x 13 x 14 x 15 x 16 x 17 x 18 x 19 x 20 x 21 x 22 x 23 x 24 x 25 x 26 x 27 x 28 x 29 x 30 x 31 x 32 x 33 x 34 x 35 x 36 x 37 x 38 x 39 x 40 x 41 x 42 x 43 x 44 x 45 x 46 x 47 x 48 x 49 x 50 x 51 x 52/(1 x 2 x 3 x 4 x 5) x (1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12 x 13 x 14 x 15 x 16 x 17 x 18 x 19 x 20 x 21 x 22 x 23 x 24 x 25 x 26 x 27 x 28 x 29 x 30 x 31 x 32 x 33 x 34 x 35 x 36 x 37 x 38 x 39 x 40 x 41 x 42 x 43 x 44 x 45 x 46 x 47)
= 48 x 49 x 50 x 51 x 52/120
= 311875200/120
52C5 = 2598960
Hence,
52 choose 5 equals to 2598960
