to calculate success probability of proxy in class which is 50% absent

Requirements:a lot of confidence,ample amount of guts,a bench in middle of classroom
Theory: in colleges and universities, bunks and attendance shortage is the most common phenomenon.
Mathematically,the probability of getting attendance short is given by:
P(A.S.)=number of bunks/proxy factor.
As proxy factor increases in the magnitude ,the probability of getting attendance short decreases.
Proxy factor is also dependent on various factors like unity among batchmates,experience of “proxy king”,etc.
The risk for “proxy king increases as the number of already given proxies increases . the experiment become almost impossible if number of the students authentically present in the class are less than 50%.
Procedure:
1.select a suitable bench(especially bench in the middle.)
2.give your own attendance in very soft voice because that is safe call for you.
3.while making proxy,look into the eyes of lecturer with full confidence.
4.as soon as target roll number is called, give a loud reply with your right hand waving in air. Don’t lose your confidence at this moment otherwise explosion may take place.
5.to make multiple proxies,hide your face behind any other student and change your pitch drastically.
Obsevations and calculations:
Total number of students=N
Number of students present=N/2
Total experienced proxy masters in the class=a(say)
Total unexperienced proxy masters=b(say)
Thus,probable success rate of proxy is given (in ideal situation ) =0.25*(a+0.25*b)/total number of proxy clashes
Precautions:
1. Do not mess with attentive and highlt tempered teacher.
2. If caught,search for innovative excuse.
3. Don’t repeat the steps 4 and 5 is someone has already got caught.
4. Keep changing your seat while making multiple proxies.
5. Be careful while making proxy of a guy absent on previous day.
Sources of error:
1. clashes between proxies of two or more proxy masters.
2. If third person laughs in betwwen the roll call.
3. Repitition of same roll number by the lecturer more than once.
