HELP BEFORE TIME RUNS OUT!! A marble is selected at random from a jar containing 50 red marbles 20 yellow marbles and 30 green m
arbles find the theoretical probability that it is either red or green. Just give me the answer and explain. I don't have time to work it out with someone!!
The answer actually is 4,245 BUT that is the correct way to do it because you take the smaller population away from the larger population in order to find their difference in sizes.
