Christmas maths question backlash

you don't have a very basic logic here. do you know that? read my post above.

Your post was in froonglish or something as it made no sense. (if it does not have uncertainty, how that can be "certainty ")

Probability has a definition - mathematically.
P, the probability function, has possible values from 0 to 1.
0 means that the event CAN NOT happen. 1 means IT WILL happen. 0.5 means there's a 50% chance of the event happening.

SO an event with P of 1 is a certainty - its PROBABILITY FUNCTION comes out to 1.

So even guaranteed events have a probability. So referring to certainties in questions around probabilities is 100% valid.

did you read this?????

=====>

if it does not have "uncertainty", then how that can be "certainty ".

or you can't read or something?

probability must be in the situation of uncertainty then you may apply probability theory. otherwise => NO

so that is the reason why it is NOT a probability question.

GOT IT?

Nope, not got it.
There DOES NOT have to be uncertainty for an event to have a probability.

P=1 means the event is certain, as defined IN PROBABILITY THEORY.


Probability is a way of assigning every "event" a value between zero and one, with the requirement that the event made up of all possible results (in our example, the event {1,2,3,4,5,6}) be assigned a value of one. To qualify as a probability distribution, the assignment of values must satisfy the requirement that if you look at a collection of mutually exclusive events (events that contain no common results, e.g., the events {1,6}, {3}, and {2,4} are all mutually exclusive), the probability that at least one of the events will occur is given by the sum of the probabilities of all the individual events.[5]
The probability that any one of the events {1,6}, {3}, or {2,4} will occur is 5/6. This is the same as saying that the probability of event {1,2,3,4,6} is 5/6. This event encompasses the possibility of any number except five being rolled. The mutually exclusive event {5} has a probability of 1/6, and the event {1,2,3,4,5,6} has a probability of 1, that is, absolute certainty.

FROM THE WIKI PAGE ON PROBABILITY THEORY.

So the event space here is that {"Christmas = 25th";"Christmas != 25th"} - which is a collection of mutually exclusive events. Probability that at least one of the events will occur is given by the sum of the probabilities of all the events (1,0)=1.

So there's your problem, defined in probability mathematics.
Got it?

Seriously ?

This is a matric question ?



Grade 3s could answer that 99 out of 100 times.

Are you sure that a kid that young would really understand those definitions 100%

I'm sure they know that dec 25 is christmas but do the understand the difference between certain and most likely (or when its appropriate to use them)

To me its more an English question

Oh my GOD!!!!!

is you mother a woman?
a) certainty,
b) may be,
c) you don't know.

you think it is a probability question?


PS: {"Christmas = 25th";"Christmas != 25th"} - which is a collection of mutually exclusive events. your example is meaningless.

Probability (or likelihood[1]) is a measure or estimation of how likely it is that something will happen or that a statement is true. Probabilities are given a value between 0 (0% chance or will not happen) and 1 (100% chance or will happen).[2] The higher the degree of probability, the more likely the event is to happen, or, in a longer series of samples, the greater the number of times such event is expected to happen.

These concepts have been given an axiomatic mathematical derivation in probability theory, which is used widely in such areas of study as mathematics, statistics, finance, gambling, science, artificial intelligence/machine learning and philosophy to, for example, draw inferences about the expected frequency of events. Probability theory is also used to describe the underlying mechanics and regularities of complex systems.

it is absolutely useless and waste of time to apply probability theory to any well known fact.

@Sinbad, your problem is to set up a probability question to find out whether or not "1 + 1 = 2", it is completely waste of time. It is NOT necessary and everyone knows the answer "your mother is a woman." (may be you want to tell I am wrong. :D)

understand?

Use the most drama when you are the most wrong.

Dreamking do you have any formal education in statistics or probability?
 
Sorry, I don't get involved in pissing contests with random Brakpan specials :o
