        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?
