If matter is neither created nor destroyed, how can the universe, with all it's matter (stars, planets, etc.), be formed from "nothing," as astronomers tell us? First there was nothing, then a giant explosion, then the universe formed. Seems to violate the laws of conversation of mass and energy, doesn't it? What am I missing?

The concept is purely mathematical. Don't worry about the engineering terms! i thought this was easy but i've looked at my answer again and i get 2 different ones. Any help much appriciated. The question is:

A and B represent 2 footings resting on soil. Each footing may remain level OR settle 5cm.

The probability of settlement in each footing is 0.1

HOWEVER, the probability that a footing will settle given that the other has settled is 0.8

WHAT IS THE PROBABILITY OF SETTLEMENT?
