somethings we are pretty sure that...
1. all number carry the same probability to be occured;
2. In long run, all number appear with same frequency.

So, if we observe some number are seriously under played, does it means this number is going to appear much more frequent than other number?

Anyway, one more phenomena ( I call it random number distribution) is that, given a game with 100 option (100 number), after 100 plays, almost 33% of the number will not be played, and slightly more than 41% of the number will be played once, 20.5% plays twice, 5% plays three times, 0.6% plays 4 times, 0.03% plays 5 times.

It can be proved easily, however, I feel upset that with such a distribution, we still can't predict the probability a random number will be played next time.

Hope any brilliant guy could share their insights here - to predict a random number. :o)

Ix-1I is an absoloute value, I could not find a symbol on the keyboard so I used a capital "I" inplace.

Also:

Solve the inequality:

I2x+3I <= 2

"It reads abosolute value 2x plus 3 is less than or equal to 2"
