Solution: The total number of permutations of 6 chimpanzees is $6! = 720$. To count the number of arrangements where Kali and Momo are adjacent, treat them as a single entity. This gives $5!$ arrangements, and Kali and Momo can be ordered in 2 ways, so $2 imes 5! = 240$. Subtracting from the total: $720 - 240 = 480$. - Treasure Valley Movers
