1) You would pick odds b/c the probability of getting two numbers that have the sum of an odd number are higher than the chances of getting an even one.
2) Tim could break it 3/3/4, 2/2/6, 1/1/8, 4/4/2. (4 ways)
3) A= bxh(1/2) A= 4 x 4 (1/2) A= 8 in
4) You'd need 74 cubes because to get that # u have to multiply 37 by 2. You need to do that b/c you also need to do that for 2 stairs up and down(2x2=4), 3stairs up and down(3x2=6), etc. so u automatically assume there's a pattern that needs to be followed.
