If you have to guess a number 1-5, and only one of them is correct, there is a 20% chance to guess correctly, I got that so far.

So, the number 1-5 that you have to guess is always random. Is there a way to find some pattern in it?

I mean, If "2" is the random number you need to guess, 4 times in a row, isnt the % chance it will be 2 again actually lower than 20%?

How can you find the number with the highest %chance of being correct if you have a long string of the random numbers 1-5
