Answer:
1260 distinguishable permutation
Step-by-step explanation:
Formula of Distinguishable Permutation:
Word = concern
P = n! / p!q!r!s!...
P = 7! / 2!1!2!1!1!
P = 7×6×5×4×3×2×1 / 2×1×1×2×1×1×1
P = 7×6×5×3×2
P = 1260

Answer:
1260 distinguishable permutation
Step-by-step explanation:
Formula of Distinguishable Permutation:
Word = concern
P = n! / p!q!r!s!...
P = 7! / 2!1!2!1!1!
P = 7×6×5×4×3×2×1 / 2×1×1×2×1×1×1
P = 7×6×5×3×2
P = 1260
P = 7! / 2!1!2!1!1!
P = 7×6×5×4×3×2! / 2! 2!
(cancel a 2!)
P = 7×6×5×4×3/ 2
P = 1260
