• I all the sudden just want to watch brave.
• So if you were to design a humanoid type robot(2 arms and 2 legs along with a head and body) the number of robots you could make would be expressed by this formula:

where Arm, Leg, Head, and Body represent the number of different types of arms, legs, heads, and bodies right or am I missing something in those squared terms?
• To find the combinations of the different body parts, you need to use the combination formula for each body part: n! / r!(n-r)! Use this formula for each of the body parts, and then multiply the answers of each formula to get the total combinations possible.
