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!
= × ( 5 × 4 × 3 × 2 × 1 )
= × ( 5 × 4 × 3 × 2 × 1 )
= × 120
= 1082161080
