Imagine a game where you and an opponent alternate with choosing bits for a binary number, until the number has 3 digits. If the resulting number is prime, you get points equal to its value, otherwise you lose points equal to its value. Draw the game tree for this game. What is your best first move?
Example:
You pick 0, your opponent picks 1, then you pick 1. The number is 011 in binary, or 3 in decimal, so you get 3 points.

Say we have 3 spheres, S1, S2, and S3, each with radius 3. S1 is located at (0,0,0), S2 is located at (0,-4,3), and S3 is located at (3,0,4). Which of these sphere intersect, if any?
Let there be a sphere S1 at (8,4,2) with radius 5, and another sphere S2 with radius 1 at (0,0,0). S2 then starts moving in x-direction with 1m/s. At what time do the two spheres collide?
Let there be a sphere S1 at (8,4,2) with radius 5, and another sphere S2 with radius 1 at (0,0,0). S2 then starts moving in x-direction with 1m/s. At what time do the two spheres collide?
You can take the position of S2 as (t,0,0), and find the (smaller) value for t for which the two spheres collide.
