The number of ways for arranging is n!
Total sample = 30+20+18
= 68
Number of ways to arrange
= 68!
= 2.480035542437 x 10^96
You can say 1/2 = 8/16 so the answer is : 9/16 + 8/16 = 17/16 = 1.06 :))
i hope this is helpful
have a nice day
Correct me if I’m wrong but I think it’s C
1 yard ≈ 0.9144 m
Therefore,
10 yards = 10*0.9144 m = 9.144 m
13 yards = 13*0.9144 m = 11.8872 m
Area to be covered = 9.144*11.8872 = 108.697 m^2
Therefore, Samantha will require approximately 109 m^2 of carpet.
