How many variations of a sequence 6 digits long made of 0s and 1s?
Q. How many possible variations are there of a sequence 6 digits long (###) where each digit can be a 0 or a 1? And how would you work it out?

A. There are two choices for the first digit; two choices for the second digit; and so on up to the sixth digit. The fundamental counting principle states that you multiply the choices together to find the possibilities, so... 2*2*2*2*2*2 = 2^6 = 64 possibilities.

Do you think animals within the same species have different variations of faces like humans do?
Q. Whenever I see a robin, I've noticed that they all look the same and cannot tell the difference between other robins. With humans, we notice the differences immediately. Do animals have different variations of faces like humans?

A. That's funny, I was wondering the same thing the other day. I think that it's just between the same species. Like how humans have different faces, maybe robins (and other birds, etc) see each other's faces as different. I think that maybe it's because it's their own species, they might notice minor differences more than we do...? Now I'll be thinking about this all day, it's so interesting. (:
