After that you need to run a probability set on all the possible combinations, with the unknowns for his paper and scissors, only knowing that they total to 50%.
what happened to live and let live?
This is someone who has documented history of not being able to do so. Instead of just letting other people live they way they want to, he is spending money and political clout to force others to live only the way he wants people to live.
Many places have had wages taken so high that there is insufficient teacher presence in halls, yards and stairwells that bullying flourishes in these areas, and this bullying chills many black students into mediocrity.
I think you are reading more into the issue than "high wages" for teachers causing a lack of teachers. If teachers charged the city/state like lawyers do for every minute that they worked, you would see that teachers are far from underpaid even at your "wages taken so high" rates that you currently claim. Even with summer "off", and not including time spent at "teacher meetings" or pre/post school year, teachers in primary and secondary schools work on average just 100 hours less than a person with a 40 hour work week does across the entire year. If the pre/post school year time, and days that teachers are required to report when students do not are included, teachers work more hours during the 180 day school year than a normal person does across the entire 260 day work year.
To be quite honest, I think teachers should be paid by the minute, just like lawyers charge. Maybe then we might actually have teacher salary that reflects the work they put in and people like you would see the actual time spent to do the job. Remember, when the students go home, the teachers still need to grade assignments/tests, create tests, update lesson plans, student learning plans, input grades into school grading software, possibly hold office hours for after/before class assistance, hold shifts covering detentions, call parents, hold parent teacher conferences, etc., etc.. All of which adds up to a lot of time over the 6 hour 40 minute "school day" that you think is the end of the time a teacher needs to be on the clock...
If the security industry at large actually knew what they were doing, websites wouldn't be instituting such asinine password rules, and my own employer wouldn't have recently cited "industry standard practice" as a reason for requiring I include special characters in my domain password.
But the security industry does know what they are doing. The "industry standard practice" for special characters is to limit the ability of a brute force attack of your password. By requiring a special character, they increased the search space needed to find the password. For an 8 character length password requiring lower case letters, there are 8*26 possible passwords. Add upper case letters, and there are 8*52 possible passwords. Add numbers and there are 8*62 possible passwords. Add special characters and there are 8*94 possible passwords. This requirement fights a specific type of attack vector.
Are there other attack vectors? Sure, and they too have their own security rules to mitigate the chances of a successful attack.
