Repeated letters are not written again in a set, so we get (S,T,A,I,C).
Step 3
Exam Tip
In roster form, order and repetition do not matter. चरण 1: शब्द में आने वाले अलग-अलग अक्षर पहचानें। चरण 2: समुच्चय में दोहराए गए अक्षर फिर से नहीं लिखे जाते, इसलिए (S,T,A,I,C) मिलते हैं। चरण 3: सूची रूप में क्रम और पुनरावृत्ति दोनों महत्वपूर्ण नहीं माने जाते।
There are (10) letters with (S) three times, (T) three times and (I) twice, so the count is (10!/(3!3!2!)). For long words, make a frequency table.
Step 2
Why this answer is correct
The correct answer is A. (50400). There are (10) letters with (S) three times, (T) three times and (I) twice, so the count is (10!/(3!3!2!)). For long words, make a frequency table.
Step 3
Exam Tip
(10) अक्षरों में (S) तीन बार, (T) तीन बार और (I) दो बार है, इसलिए संख्या (10!/(3!3!2!)) है। बड़े शब्दों में आवृत्ति तालिका बनाएं।
(S) appears three times, (T) appears three times, and (I) appears twice. In exams count letter frequencies before word arrangement.
Step 2
Why this answer is correct
The correct answer is A. (3!3!2!). (S) appears three times, (T) appears three times, and (I) appears twice. In exams count letter frequencies before word arrangement.
Step 3
Exam Tip
(S) तीन बार, (T) तीन बार और (I) दो बार आता है। परीक्षा में word arrangement से पहले letter frequencies गिनें।
