What is a probability of a not event?
Can someone please answer this
How do you calculate the statistical probability of dying in a plane crash?
You calculate the statistical probability of dying in a plane crash in the same way that you calculate the probability of anything else. You simply divide the number of expected outcomes by the number of possible outcomes. To determine the statistical probability of dying in a plane crash, you divide the number of people that have died in a plane crash by the number of people that have flown in planes. You can aggregate this anyway you want, over whatever period of time you want, so long as you properly state the conditions under which you perform your calculation.
What is an example of a result that would have a probability near 0 percent?
All life on earth dying out by the end of this year.
What is frequency approach to probability?
The frequency approach or experimental probability involves the estimation of the probability of an outcome as the proportion of "successful" outcomes in repeated trials. I put "successful" in quotes because in epidemiology, a "successful" outcome is often a person catching a disease or infection and possibly dying as a result. I am not sure if anyone would consider that a success!
What is the probability of testing positive for the disease?
The probability isP(you have the disease)*P(the test shows positive when testing someone with the disease) +P(you don't have the disease)*P(the test shows positive when testing someone without the disease).The second category is particularly important if the disease is rare but the probability of a type II error is large.
