1. Mess between probability, as a measure of variability of object, and confidence degree, as a measure of the information on object
The first concerns likelihood process, for example, to radioactive disintegration, and the second to unknown process - for example, to card guessing. However global risks concern the phenomena, estimating which we are compelled to state likelihood judgments about processes, which simultaneously both likelihood, and unknown to humans. Here we start to speak about degree of confidence of this or that probability. In this case the probability and confidence degree are multiplied.
