Answer:
There are 924 possible combinations
Step-by-step explanation:
Total Number of marbles = 12
Number of marbles to be selected = 6
We are supposed to find the number of possible combinations .
So, we will use combination .
Formula: [tex]^nC_r =\frac{n!}{r!(n-r)!}[/tex]
n = 12
r = 6
Substitute the values in the formula :
[tex]^{12}C_6 =\frac{12!}{6!(12-6)!}\\^{12}C_6 =\frac{12!}{6!6!}\\^{12}C_6 =924[/tex]
Hence there are 924 possible combinations
