The Role of Probability. Basic Concepts of Probability. A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Thus, when people hypoventilate (i.e. causing an increase in CO2) this causes the pH in your blood to decrease, making it more acidic. (and when hyperventilation occurs, O2 is increased, which causes an increase in pH - making blood more basic).
Ironically, despite spending a lifetime walking around in the same body and doing our best to care for it (or wishing we would), few seem to wonder what happens to their physical remains right after death occurs. 1  Here is a timeline of the processes involved, assuming the deceased remains undisturbed. At the moment of death, all of the muscles in the body relax, a state called primary flaccidity. Eyelids lose their tension, the pupils dilate, the jaw might fall open, and the body's joints and limbs are flexible.
