How do you give the probability of a sum?
You find the event space for the random variable that is the required sum and then calculate the probabilities of each favourable outcome. In the simplest case it is a convolution of the probability distribution functions.
If an event has a 1 in 4 chance of occurring what is the probability of it happening to one individual in a sample of five?
If we assume that the probability of an event occurring is 1 in 4 and that the event occurs to each individual independently, then the probability of the event occurring to one individual is 0.3955. In order to find this probability, we can make a random variable X which follows a Binomial distribution with 5 trials and probability of success 0.25. This makes sense because each trial is independent, the probability of success stays constant for each trial, and there are only two outcomes for each trial. Now you can find the probability by plugging into the probability mass function of the binomial distribution.
What is the probability of an event b that impossible?
The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.
Define p-value vs - z score?
The p-value is the probability of any event or the level of significance for any statistical test. The z-score is a transformation applied to a Random Variable with any Normal distribution to the Standard Normal distribution.
How do you find the probability of the complement of an event?
The probability of the complement of an event, i.e. of the event not happening, is 1 minus the probability of the event.
What is the standard deviation of a geometric random variable x for an event with a probability of success of 0.75?
It is sqrt[(1-p)/p2] = 0.666... recurring.

Is the expected value of a random variable more cumbersome to work with then an objective probability distribution?
Not necessarily. The answer depends on the event under consideration.Not necessarily. The answer depends on the event under consideration.Not necessarily. The answer depends on the event under consideration.Not necessarily. The answer depends on the event under consideration.

Where is probability found?
Wherever there is some random (that is, non-determinate) element in the occurrence of an event.
What is the mathematical definition of random?
There are a number of definitions. In mathematics, it depends on the context that the word is used. One definition is for a "random event" where all outcomes are equally likely to occur. A random selection of lottery numbers means that in the long run, no one number is likely to occur more than another one. Random events are typically considered independent random events, in that one event can not affect the outcome of another one. A "random variable" means that the probability of any value occurring corresponds to a given probability distribution function. There is a common use of random, which means to act without a plan.

What does it mean when you say that diffusion is simply a probability phenomenon?
It means that the motion of every molecule of a fluid is random and the location of all the molecules comprising the fluid, after a period of time, is a random event or a probability phenomenon.

What is the probability of an event b that impossible?
The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.
What is the definition of geometric probability?
Geometric probability is the probability of a random event within taking place a geometric plane. The idea of geometric probability covers a wide range of problems, but the common theme is probability as it applies to geometric shapes and objects.
What is the probability of 180 and 60?
The question is under-specified. The variable is not defined, the event space is not defined, the experiment is not defined.
Define p-value vs - z score?
The p-value is the probability of any event or the level of significance for any statistical test. The z-score is a transformation applied to a Random Variable with any Normal distribution to the Standard Normal distribution.
