Answer:
( ¹⁵C₂ )² × 5! = 1082161080
Explanation:
Data provided in the question:
Number of married couples = 15
Therefore,
Number of males = 15
Number of females = 15
Now,
The number of possible dancing arrangements
= Probability of selecting males × Probability of selecting males × ways of arranging 5 pairs
= ¹⁵C₂ × ¹⁵C₂ × 5!
= ( ¹⁵C₂ )² × 5!
= ![[\frac{15!}{5!\times(15-5)!}]^2](https://tex.z-dn.net/?f=%5B%5Cfrac%7B15%21%7D%7B5%21%5Ctimes%2815-5%29%21%7D%5D%5E2)
× ( 5 × 4 × 3 × 2 × 1 )
= ![[\frac{15\times14\times13\times12\times11\times10!}{5\times4\times3\times2\times1\times10!}]^2](https://tex.z-dn.net/?f=%5B%5Cfrac%7B15%5Ctimes14%5Ctimes13%5Ctimes12%5Ctimes11%5Ctimes10%21%7D%7B5%5Ctimes4%5Ctimes3%5Ctimes2%5Ctimes1%5Ctimes10%21%7D%5D%5E2)
× ( 5 × 4 × 3 × 2 × 1 )
= ![[\frac{360360}{120}]^2](https://tex.z-dn.net/?f=%5B%5Cfrac%7B360360%7D%7B120%7D%5D%5E2)
× 120
= 1082161080
