In how many ways can you choose 2 pairs of jeans?
Step 2:
The details of the solution are as follows:
From this question, we can see clearly that this is an application of selection under combinatorial analysis:
[tex]n\text{ C}_r=\text{ }\frac{n!}{r!(\text{ n - r \rparen}!}[/tex][tex]\begin{gathered} Now\text{, we have that:} \\ \text{n = 5} \\ \text{r = 2.} \\ Then,\text{ we have that:} \\ 5\text{ C}_2\text{ = }\frac{5!}{2!\text{ \lparen 5- 2\rparen}!}=\text{ }\frac{5!}{2!3!}=\frac{5\text{ x 4 x 3}!}{2!\text{ x 3}!}=\frac{20}{2}=\text{ 10 ways} \end{gathered}[/tex]CONCLUSION:
The final answer is:
[tex]10\text{ ways}[/tex]
