The notation (9C4) represents the number of combinations of 9 items taken 4 at a time. It is calculated using the formula ( \frac{n!}{r!(n-r)!} ), where ( n ) is the total number of items, ( r ) is the number of items to choose, and ( ! ) denotes factorial. Therefore, ( 9C4 = \frac{9!}{4!(9-4)!} = \frac{9!}{4!5!} = 126 ). Thus, ( 9C4 ) equals 126.
What else can I help you with?
How many 4 number combinations can you make with numbers 1-9 and without having any repeating numbers?
There are 9 choices for the first digit, 8 for the second, 7 for the third, and 6 for the last. So there are 9x8x7x6=3024 "permutations" That means the order does matter. If the order does not matter, divide that number by 4!=4x3x2x1 9C4 is 126
