If the probability that an event will occur is three eighths then what is the probability that the event will not occur on the first trial and not occur on the second trial?
This question does not have a unique answer unless we make an additional assumption: we must know something about the relationship between the trials. For example, if we are monitoring a lightbulb for failure and the "event" consists of a working lightbulb, then the event not occurring means the lightbulb doesn't work. Let the "trials" consist of turning on the lightbulb. If the bulb fails on the first trial (chance of 1 - 3/8 = 5/8) then obviously it will not work on the second trial, either. The answer in this case would be 5/8 = 62.5%. If we assume the two trials are statistically independent, we are really saying we don't want to worry about these issues. Equivalently, the person asking the question is just telling us to multiply the probabilities (which means they are probably a teacher or a textbook and they or it are mainly concerned about your ability to multiply fractions, not about your understanding of probability). The chances of the event not occurring in each trial are 5/8. Multiplying gives 25/64 = about 39%. This is quite a bit less than 62.5%.
Does the probability of failure vary from trial to trial under binomial distribution?
No. It must remain the same.
If two events are mutually exclusive what is the probability that both occur at the same time?
The probability is 0. Consider the event of tossing a coin . The possible events are occurrence of head and tail. they are mutually exclusive events. Hence the probability of getting both the head and tail in a single trial is 0.
The chance that a given event will occur usually expressed between the number 0 will not occur and 1 the event will occur is called?
The chance that a given event will occur, usually expressed between the number 0 (will not occur) and 1 (will occur) is called probability.
Does Probability predict what will definitely occur?
The laws of probability predict what is likely to occur, not necessarily what will occur.
Do floods occur in Central America?
Very rarely
What events occurred after the arraignment and before the trial in the Scott Peterson case?
As with any case that will go through a jury trial, the time between the arraignment and trial is a busy time for the attorneys. There is analyzing evidence, interviewing wittneses, discovery, jury selection and a multitude of preliminary issues before the judge. This is also the time for any paid experts to be flown in if needed and all parts of the trial from beginning to end to be examined by both prosecution and defense so there are no surprises. Trial attorneys hate surprises. Most attorneys have already written their closing aurguments before jury selection.
How do you gain brains quickly zombie farm?
Sometimes it's just luck! But you get them from either daily surprises (rarely). You can also get them from invading (it tells you how lucky you are before you invade)
During what stage of a trial do direct examination and cross examination occur?
Direct examination and cross examination occur during the trial phase known as the presentation of evidence.
Does evaporation of ocean water rarely occur?
No, it evaporates all the time.
What is a disjoint events mean?
In probability theory, disjoint events are two (or more) events where more than one cannot occur in the same trial. It is possible that none of them occur in a particular trial.
What year did the original trial of the Scottsboro Boys occur?
1931
What does unfavourable outcome mean?
It is an outcome of a trial in which the event of interest does not occur.
Do natural disasters occur in Antarctica?
yes but rarely, like blizzzards, and icequakes.
