      @The-Darkin-Blade You're right, it's not exactly the golden ratio... maybe we should make it a rectangular cake with length 16 inches and width 10 inches 🙂

        We should add an extra part: We made a cake that is 62.28 inches in diameter because Prof. Loh deserves a special cake. How much space (volume) will the cake take up?

          Another problem:
          Bob the baker 🐱 is back!
          He baked 28 small cakes that could bear the symbols: P,O,-,S,H,E,N,L,O,H,6,/,1 or 8. He generate a random symbol from the above list for each cake and put the symbols on them. (Yes, the letter O and H have the highest probability of 1/7 each, while the others 1/14 each)
          But he accidentally messed up the cakes and have to randomly re-order them.
          Then he uses Baker Cat Magic and have a 16.18% chance of switching the symbol on the cake currently to the next (ie P to O, S to H etc). O and H have 8.09% chance of going to - and 6 with the same chance for going to H and E, respectively.
          Or else the symbol stays the same. The same applies for all symbols.
          What is the chance that, in the end, it spells “PO-SHENLOH6/18PO-SHENLOH6/18” ?

                  Bob the 🐱’s bakery was a success!
                  He cooperated with three big 🍰 companies - Po, Shen and Loh - to celebrate Professor Loh’s birthday.
                  On June 18th, the three companies makes random # of cakes between 24 and 618. Every possible # of cakes have equal chance. Then they press letters on each one.
                  Po company: 61.8% chance press P, 38.2% chance press O.
                  Shen company: 6.2% chance press S, 93.8% chance press H, E or N.
                  Loh company: 81.6% chance of press L, 18.4% chance press O or H.
                  Then they choose the best cake on display. Each cake have the same chance of being on display. Bob the 🐱 take photos of the three displays and shuffles them into random order.
                  What is the probability that the photos spell Professor Loh’s initials (PSL) in the same order?
