How determine probablity for mutually exclusive events?
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.
Differences between probability samplingand non-probability sampling?
the difference is just that non-probability sampling does not involve random selection, but probability sampling does.
What is the probability of getting 2 heads if a coin is tossed thrice?
(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.
What is the probability that they you will get two heads when you toss two coins?
If you toss them enough times, the probability is 1. For just one toss the probability is 1/4.
What could the acronym 'TULIP' mean in a maths sense - my probability lecturer keeps using it?
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.
