What  is the mathmatical chance that an event will occur??

none without time, infinite with time.

Yes, the probability of life happening is 1 because it happened.  I would guess that looking from the outside, the probability that someone named icarus62 typed the following "Apologetics...." at exactly [insert time here] using whatever type of computer, etc. is also arbitrarily small but it did happen. :)

Is the term you are looking for "probability"?\n\nI hope this helps.

it's pretty complicated, and I'm too far removed from my math courses to keep it all straight.  But it varies based on what your point is, simply because some outcomes are more likely.\n\n4 has 3/36 odds of being the point\n5 has 4/36\n6 has 5/36\n8 has 5/36\n9 has 4/36\n10 has 3/36\n\nBut you can't roll 7.  So if we assume the point is 5, for each roll there is 32/36 odds that we don't roll 5, but 6/36 odds we roll a seven.  Reconcilling that involves equations that I've long since forgotten about.\n\nI think maybe [((8/9 - 1/6)^11)*(1/9)] would be the odds you'd roll 11 times without getting 7 or 5 and get a 5 on the 12th roll.  That'd be about .0214.  That you'd follow that up with a 7 or 11 would be .0214*(8/36), or .00535\n\nSite I link to be low discusses the outcomes a bit more formally than I'm cabaple of doing these days.

I'm assuming you are talking about a probability problem in Bayes' theory since you haven't specified what any of your symbols mean. This is why there are no responses.\nThe answer is actually quite clear. Draw three circles in a triple intersection for the events R, S and I and label it clearly. The diagram simplifies to a certain double intersection that motivates the result.

I am a teacher of mathematics and in a 31 year career I have had it happen to me exactly 1 time!!! It is a very very low probability

yea, multiplying the single event probabilities of two independent events to get the prob of the independent events conjunction is correct. In other words (to avoid you going to grab an Advil already): p(A&B)=p(A)*P(B) assuming A and B two independent events. That's BASIC stats.\n\nIn excel, use the function POWER. First argument the probability, second argument the number of occurence in a row.

The probability of A is 26%.  Probability of B is 42%.  Both A and B is 7%.  Probability of neither = 100% - [(26%+42%)-7%] = 39%.  Or in your format, 0.39.

Yes i can say there are so many events that you can believe 50/50 chances.\n\nAs you said 50/50 is calculating for 100. means you have 2 chances.\n\n1. Toss the coin: to get head or tail you have 50/50 chance\n2. If a women is giving birth: the baby may be BOY/GIRL 50/50 Chance\n\n3. for this question : someone give the answer: which is correct/not correct   50/50 chance.\n........... \nyou can find somany events which are having 50/50 chances

Considering  possible events are\nChoosing heads \nChoosing tails \n\nprobability of chosing heads is 0.5\n\nConsidering possible events are\nChoosing heads \nChoosing tails \nChoosing Nothing\n\nprobability of chosing heads is 0.33\n\nConsidering possible events as only heads because next is tails\nprobability of chosing heads is 1.\n\nprobability is always a value betweem 0 and 1.

Probability of getting one head = 1/2\nProbability of getting two heads = (1/2) * 2 = 1/4\nYou have a 25% chance of getting a head two times...\nAnd 12.5% chance of getting a head 3 times...\nAnd 6.25% chance of getting a head 4 times...\n.\n.\n.\nAnd 0.09765625% chance of getting a head 10 times!!! :)

1% chance of that happening\n\nso Im not THAT worry like the others

the chances are very small but know one nows \n \n\n\nimpossible to answer this question

If you want a number less than three,then the likely numbers are:1 and 2\nThe probability of throwing a 1 is 1/6\nThe probability of throwing a 2 is 1/6\nThese two events are mutually exclussive,therefore sum up their respective probabilities. \n1/6+1/6=1/3\nSo,the probability of obtaining a number less than 3 is 1/3

From theoritical point of view it exist..Because it includes a infinite no of trials which is valid in books.But practically a probability can't exist because  to find out the proper measure we have to carry on the experiment for infinite times which is impossible(even for a idle guy like me).\n  It is measured by the equation of P=(favourable outcomes)/(total outcomes).for a n trial experiment and then tend n to infinite.\n  Just like a coin toss.We assume that if we toss the coin for infinite times the above fraction would be half.\n Although practically it may seem for 10 experiment you get 6 H and 4 T (if ur luck is bad u may find a 10:0 ratio also.)\n  So probability depends on the deterministic behaviour solely not on randomness or non determinism.

The answer is one chance in 2^5  or 1 in 32.\n\nNotice that the chances are the same as flipping five heads in a row.
