Answer:
180
Step-by-step explanation:
SERIES There are 6 letters in the word ‘SERIES’ out of which 2 are S’s, 2 are E’s and the rest all are distinct. Therefore by using the formula
, n!/ (p! × q! × r!)
The total number of arrangements
= 6! / (2! 2!)
= [6 × 5 × 4 × 3 × 2 × 1] / (2! 2!)
= 6 × 5 × 3 × 2 × 1
= 180
