You can put this solution on YOUR website! There are 7 boys and 3 girls in gathering. In how many ways can they be arranged in a row so that the 3 girls form a single block
------------------
Assuming no differences in the 3 girls in the block:
---> 8 elements
=====
1 of 8, then 1 of 7, .... etc
8*7*6*5... = 8!
8 factorial. Not an excited 8.
