• 3 girls can be selected from 15 girls in 15C3 ways.
  
  Therefore, total ways = 12C2 * 15C3
  
  Suppose we take 1 of the 12C2 group of boys. This group can be attached to any of the 15C3 girls. Thus, we can do the same for any of the 12C2 groups... So we multiply..

• we can select 2 boys from 12 boys and form 12c2 combinations
  we can select 3 girls from 15 girls and form 15c3 combinations
  therefore, total dance forms that can be formed are .... 12c2 * 15c3 = 30030
