yes. you have a 50% chance
True
False.
False.
True
There are two answers to this question. If it can only land on heads or tails up, then there is a 50% chance ( or half a chance) it will land heads up, but that's not necessarily true. But, if it can land on heads, tails, or sides, then there is a 16% chance it will land tails up.
False. We are often exposed to low dose radiation.
TRUE
False
True AND False OR True evaluates to True. IT seems like it does not matter which is evaluated first as: (True AND False) OR True = False OR True = True True AND (False OR True) = True AND True = True But, it does matter as with False AND False OR True: (False AND False) OR True = False OR True = True False AND (False OR True) = False AND True = False and True OR False AND False: (True OR False) AND False = True AND False = False True OR (False AND False) = True OR False = True Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention. This makes the original question: True AND False OR True = (True AND False) OR True = False OR True = True
false. Fish move their tails side to side to aid motion. However, whales were once land animals and their spines are built differently. To be able to move with that physical set up, their tails move up and down.
The articles are decently accurate but there is a high chance of something being false.
False. It is software.
