Present continuous tense is used: for that activity, thing or action that is happening at the very moment while you are speaking about it. In other words, when you speak or discuss about the action that is happening or occurring or going on or continuing at the same time of your saying, you need to use this tense(or tense form). The action you are talking about has not started in the recent past or did not start in past but it is just happening now itself, that is, it is of shorter duration usually though there are exceptions.

This is wrong because the earth always revolves around the sun, it is not of shorter duration but it happens all the time and thus, we use simple present but not present continuous.

Mutually exclusive events: The two events A & B are said to be mutually exclusive events when they cannot happen at the same time. Thus, A & B has no intersection area since they are not occurring at the same time. P(AΠB) = P(AB) = 0 where P(AΠB) is the probability of A intersection B and it is same as the probability of A multiplied by B, P(AB). In dependent events: The two events A & B are said to be independent events when the occurrence of one event does not influence the occurrence of other event. In this case, P(A Π B) = P(AB) = P(A)*P(B), that is, the probability of A & B is the probability of A multiplied by the probability of B. Difference between mutually exclusive events and independent events: One difference is as we have seen above, if A & B are mutually exclusive, the probability of their intersection is zero. P(AB) = 0 and  if they are independent, P(AB) = P(A)*P(B). The other difference can be seen fro
