False; the "or" is an additive property so the probability of rain or snow muse be greater than or equal to 0.65.

You don't. Either you know the material or you don't. There's no good way of guessing on a true-false test.
Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False
True. A good insulator has high resistance to the flow of electricity, making it a poor conductor of electricity. Examples of good insulators include rubber, glass, and plastic.

False. Electric current is the flow of electric charge (usually carried by electrons) through a conductor, not the flow of atoms.
True. Salt water is a good conductor of electricity because it contains ions (charged particles) that can carry an electric current. This is why salt water is often used in experiments or applications that involve electricity.
True.
No, a material with high resistivity is a poor conductor. Resistivity is a property that quantifies how much a material resists the flow of electric current. Materials with high resistivity impede the flow of current, making them poor conductors.
That is false. The Sierra Nevada actually receives quite a bit of snow in the winter. The Sierra Nevada is a mountain range.
False
Very little snow falls in Antarctica. It is known as a dry region and very windy.So it is true that only little snow falls in Antarctica
