7 girls audition for 12 roles in a school play. What is the probability that at least 2 of the girls audition for the same part?

42

Step-by-step explanation:

12*7=84

84/2=42

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
