Answer:
there are 86493225 possible ways you can get a bag of 12 doughnuts
Step-by-step explanation:
since we do not care about the order of the donuts in the bag ,we will need to calculate the number of possible combinations for 30 different elements in a group of 12 , then:
Number of combinations=C= n! /[(n-r)!*r!]
where n= number of elements , r= group size
replacing values
C= n! /[(n-r)!*r!] = 30!/[(30-12)!*12!] = 86493225 possible combinations
