User blog:Wildoneshelper/Guess the number! (Round 4)

The number is the number, get it? We're now moving on to round 4 of stub! This time this round is MUCH MORE difficult. Therefore, get all your maths exercise you have from primary studies to secondary studies! All of this is about probability! (Or not)

Rules

 * Guess an 8-digit number each time, numbers starting with 0 don't count. The digit may contain letters A, B, C, D, E or F.
 * There will be two kinds of "correct". First one is "correct digit but wrong place", which will be marked with a yellow tick. Second one is "correct digit and place", which will be marked with a green tick.
 * Example, if my answer is "152", and you guess "350", my response will be 1 ✅. If you guess "125", my response will be 1 ✅, 2.
 * You could only guess one number each time. You could only guess the number again when others have guessed one time. In other words, guess one number, then wait for others to guess another number, then you can guess the number again. If the comment contains more than 1 answer, the comment will be counted as void.

Let the fun begin!
