## 2 Materials and Methods
We will disregard the biological nature of the studied events (assailant agents, interaction between agents and cells, results of such interactions) and we will only calculate the odds (probability) of such events occurring (odds of assistant agents coming in contact with cells and odds of producing chronic irreversible lesions). _Question 1--What is the probability that an assailant agent comes into contact with the cells of the D-Organ?_ This is a complete set of events formed by two complementary (incompatible, opposing) events: E1 = YES [comes into contact]; E2 = NO [does not come into contact], which leads to the equality of the two probabilities P(E1) = P(E2) = 1/2. The two events form the certain event partitioning, which means the concomitant existence of the assailant agent and _D-Organ_. _Question 2--What is the probability that once in contact to the D-Cell the assailant agent interacts or does not interact with it?_ This is also a complete set of events similar to the previous, formed by two complementary (incompatible, opposing) events: E3 = YES [it interacts]; E4 = NO [does not interact], which leads to the equality of the two probabilities P(E3) = P(E4) = 1/2. This is the certain event partitioning, which means the potential existence of interaction between the assailant agent and _D-Cells_ (implicitly _D-Function_). _Question 3--starting from the two previous answers, we propose the following problem:_  
Using the _unreplaced ball principle_, also known as _hypergeometric distribution_[7; 8] (Figure 4), let us calculate the probability of obtaining random events with the following experiment: in an urn there are 50 black balls and 100 white balls (the ratio signifies the biological defense mechanisms of the D-Cell against any type of aggression--if the assailant agent interacts with the cell, the chances of irreversible damage are 50%); we extract 100 balls from the urn without returning any of them (_the unretured ball_). Determine the probability of achieving a series of 25 independent, random events, meaning the pairs of integer numbers starting with 2 black balls-98 white balls and continuing with 4 black balls-96 white balls, 6 black balls-94 white balls... all the way to 50 black balls-50 white balls. The number of black balls represents the weight of chronically diseased _D-Cells_ (irreversible). This status is determined by the interaction between the assailant agent and the _D-cell_ population and is assessed as such at the end of all contact between the two entities. The number of white balls represents the weight of healthy _D-Cells_ (complementary), also assessed at the end of all contact between the two entities. We have axiomatically conferred to the body's defense mechanism and therefore to the _D-Cell_ also the intrinsic capacity to cut the chances of assailant success (irreversible lesions) in half: 100 white balls versus 50 black balls. This means that _Question 3_ can be stated as follows: Determine the probability of achieving a series of 25 independent, random events completely defined by 25 pairs of integer numbers representing the weight of complementary diseased and healthy _D-Cells_ (\(\text{Weight}_{\text{diseased cells}}=1-\text{Weight}_{\text{healthy cells}}\)). These 25 events represent the partition of the event \(\text{E}_{1}=\text{YES}\) [comes into contact] with an already known probability of \(\
icefrac{{1}}{{2}}\) and 25 possible manners of intensity of said aggression. These probabilities are valid for a single _D-Cell_ population forming a single _D-Organ_ located in the temporal bone of a single individual. To obtain information regarding the general human population or a segment thereof, the corresponding temporal bone population (one-side), and the corresponding _D-Organ_ population for these TBs, we must calculate the probabilities of achieving each of these 25 events this time considered as Exclusive Random Events. We shall use [PERSON]'s scheme [9; 10] (Figure 5).
