Answer to number 1: You would chose the even numbers because there are more even numbers and two odd numbers equals an even number. There is a less chance to get an odd number.
Answer for number 4: You would need a total of 1,369 cubes. To get the answer multiply 37*37 because the number of steps are squared to equal the number of cubes. If you have the number of cubes then you would find the square root to get the steps. Ex: 9 cubes would equal to 3 steps, 16 cubes equals 4 steps. If you have 16 steps you have 256 cubes.
