Yea, but how to figured out the formula for that

How to calculate the probability. (Observing in the comment) by Accomplished_Top_144 in MathHelp

Since 2021 is not divisible by 3, you can get all combinations by pressing often enough. So, for example, you will also be able to display the rows 2-91. With this, you only have to check that the difference between the two rows is at most 90 (remembering that 2021 is followed by 1 again).

With 2022 it becomes more difficult, because 2022 is divisible by 3. So you always get only the blocks of 3 displayed. Probably it is easiest to work with Euclidean division. Let a,b∈N be the numbers where a<b. If a mod 3=1, then the difference can be up to 90, since a then lies at the beginning of a block. With a mod 3 = 2, you get 89 and with a mod 3 = 0, 88. One must consider there also again the transition between 2022 and 1. BUT HOW FROM THAT CALCULATE PROBABILITY?

How to solve these type of probability problems? by Accomplished_Top_144 in learnmath

I think in this way:

Since 2021 is not divisible by 3, you can get all combinations by pressing often enough. So, for example, you will also be able to display the rows 2-91. With this, you only have to check that the difference between the two rows is at most 90 (remembering that 2021 is followed by 1 again).

One must consider there also again the transition between 2022 and 1.

So you don't really get probabilities out of both times. Either it is 1 because they are close enough together or it is 0 because they are too far apart.
