Let a b and c be independent events with pa = 0.4 pb 0.8 and pc =0.6 find pa and b and c.

15.3 cos 65 degrees trig

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
