Given the way the or operator works can adding or to a false

Given the way the ‘or’ operator works, can adding ‘or’ to a false proposition ever change the truth value of the proposition? Can adding ‘or’ change the truth value of a true proposition?

Solution

Yes, adding or can change the truth value of the proposition. for example a coin is tossed and condition is probability of getting head =1/2=0.5 . if we add or getting tail to it, truth changes now we van get both head or tail=0.5+0.5=1

Yes similarly opposite way around if getting head was true proposition adding or tail would change the truth too
