1) OVERLAP: Estimated probability that 2 poets, born in the same year [Marlowe/Shakspere] living both in London, did not timely overlapped in their literary activity a single day 1:10000 **
2) EDUCATION: Estimated probability that the universal education, languages and world knowledge of Shakespeare can not be taken from the school education from Stratford: 1: 10000
3) ARISTOCRACY: Estimated probability that Shakespeare has not resided in circles of the court and aristocracy for a single day of his life. 1: 10000
4) WILL: Estimated probability that Shakespeare did not leave a “literary” legacy in his last will 1: 10000
Based on these four individual probabilities there is a results of a (very very low) overall probability of 1: 10 000 000 000 000 000 000 (by a factor of 10 to the power of 15), that Shakspere was identical with Shakespeare. Thereby, however, it was not taken into account that one would have to integrate a hundred additional similar individual probabilities, (as shown in the QUIZ) or a multiple thereof , as shown in the book "The true Shakespeare"
[ ** this event would result 1 in 10000]
