Mutually exclusive events are considered two events that cannot coexist with one another, in other words, if the first event is happening the second just cannot. Determining the probability for mutually exclusive events can be done by using the formula P ( A and B ) = 0.
the difference is just that non-probability sampling does not involve random selection, but probability sampling does.
(1/2)^3 = 1/8th Since the initial probability (assuming independence) of getting a head in a single toss is one half (1/2) we just cube this probability because of the number of events we are performing. So if you were to try to calculate the probability of a coin being tossed 6 times it would be one half to the 6th power which is 1/64.
If you toss them enough times, the probability is 1. For just one toss the probability is 1/4.
Well, isn't that just a happy little coincidence! In probability, the acronym TULIP often refers to the five basic components of a probability problem: Total number of outcomes, Unfavorable outcomes, Likelihood, Independent events, and Probability. Your lecturer is just helping you break down probability problems into manageable parts, like painting a beautiful landscape one brushstroke at a time. Just remember, there are no mistakes, only happy little probabilities waiting to be solved.
