Mr. smith brings home 7 animals for his 7 children. each child will adopt a pet to be her or his own. there are 4 different cats (a siamese, a persian, a calico, and a minx), 2 different dogs (a poodle and a golden retriever), and a goldfish. anna and betty refuse to take care of the goldfish, and charlie and danny insist on having cats. the other 3 kids are easier to -- they'll take anything. in how many ways can mr. smith give the children pets they'll want?
