Formula for the probability of A and B (dependentevents): p(A and B) = p(A) * p(B|A) The formula is a little more complicated if your events are dependent, that is if the probability of one event effects another. In order to figure these probabilities out, you must find p(B|A...
or “bell curve,” is aprobability distributionthat issymmetricabout its center:half of data falls to the left of themean(average) and half falls to the right. The bulk of data are clustered around the central mean, which results in a bell-shaped curve when graphed. ...
(A)=0.2, P(C or D)=0.6, and P(C)=0.5 The events A and B are mutually exclusive, and the events C and D are independent. Find P(D). I'd appreciate it if someone could show me how to solve this. The answer is given as 0.2, but I don't know how it's arrived at...
The very first of the thousand steps, if you want to find something new, is to learn to live with uncertainty, and to learn to accept failure as the norm, because looking for the unknown is like being a trapeze...
Basically, I have two overlapping pdf functions, and I am trying to find the probability of the smaller pdf being greater of the other. I have generated both pdf functions from data collected. This is the code that I am using: %%Density Function ...

A p-value, or probability value, is a number describing the likelihood of obtaining the observed data under thenull hypothesisof a statistical test. The p-value serves as an alternative to rejection points to provide the smallest level of significance at which the null hypothesis would be reject...
Calculating probabilities of combined events Sometimes we want to find the probability of more than one event occurring. There are different probability rules that we can use. Mutually exclusive events Mutually exclusive events are two or more events that cannot occur at the same time. For ...
A type 1 error, or alpha, is made when H0 is rejected, when in fact H0 is true. Alpha is the probability of saying on the outcome of a test there is an effect for the manipulation, while on population level there actually is none. 1-alpha is the chance to accept the null hypothesi...
