I think starting from the top it would go as follows
9/36, 27/36, 32/36 , 4/36
b.) 9/36
c.) I really don't remember how to do the "order doesn't matter" thing anymore, so idk. my best idea is for you to look up the formulas for permutation and combinations. I know it has to do with that
2y - 3x = 4
2y = 3x + 4
y = 3/2*x + 2
y = kx + b ==>
k = 3/2 = 1,5
Because vol= length x width x height , and assuming that the height is 11.5 because breadth means width but you already have a width then, vol= 11.5 x 7.4 x 11.5, vol = 978.65
It’s c. Where the two planes intersect
