Given a wheel with A, B, C, D, where each letter has an equal chance to be landed on, when any one letter is picked four times, it is removed from the wheel (changes the chances).

Also, instead of spinning the wheel, you can choose to just take an A (given it hasn't been picked four times already)

If you have 8 spins, determine the best way to land only on A and D (4 spins on A, 4 spins on D), and the probability.


Im having trouble solving this, I tried using hypergeometric distribution but I don't think it will work because of some of the conditions (e.g you can just pick an A, and the limit for each letter is 4). Any hints on how to solve would be appreciated :>

If you choose 13 times - do you see that "some letter" will be chosen 4 times !!
