यदि \(A=\{1,2,3,4,5\}\) है तो (A) के अधिकतम दो अवयवों वाले उपसमुच्चयों की संख्या क्या है?

If \(A=\{1,2,3,4,5\}\) then what is the number of subsets of (A) having at most two elements?

Explanation opens after your attempt
Correct Answer

C. (16)

Step 1

Concept

At most two elements means (0,1,2) elements. The count is \(\binom{5}{0}+\binom{5}{1}+\binom{5}{2}=1+5+10=16\).

Step 2

Why this answer is correct

The correct answer is C. (16). At most two elements means (0,1,2) elements. The count is \(\binom{5}{0}+\binom{5}{1}+\binom{5}{2}=1+5+10=16\).

Step 3

Exam Tip

अधिकतम दो अवयव का अर्थ (0,1,2) अवयव हैं। संख्या \(\binom{5}{0}+\binom{5}{1}+\binom{5}{2}=1+5+10=16\) है।
