The addition rule for probabilities describes two formulas, one for the probability for either of two mutually exclusive events happening and the other for the probability of two non-mutually exclusive events happening. The first formula is just the sum of the probabilities of the two events. The...
What is the probability of selecting a car at random that is either red or has a radio?A. 88%.B. 76%.C. 28%. 正确答案:A 分享到: 答案解析: The addition rule for probabilities is used to determine the probability of at least one event among two or more events occurring, in this...
For any two events A and B, the probability of the event 'A or B' is computed as P(A∪B)=P(A)+P(B)−P(A∩B). If the two events are mutually exclusive, then the addition rule is simply the sum of the two probabilities, because the term P(A∩B) become...

Zhang Antian: After Biden's withdrawal, the probability of a scenario with Trump and a divergent Congress is greater than that of a sweeping victory for Trump. One reason is that Harris fits the demographic portrait of the 2024 election better, since voters from the "baby boomer" generation ...
If two events are mutually exclusive they do not have any common outcomes (one cannot occur if the other has occurred). The addition rule of mutually exclusive events is as follows: P(A∪B)=P(A)+P(B)Answer and Explanation: Become a Study.com member to unlock this answer! Cre...
Ransomware is a kind of special malware that prevents victims from accessing their systems or system data (such as documents, emails, databases, and source codes) and demands ransom payment in order to regain access. This type of attack is known as a denial-of-access attack. As the data is...
The paper is organized as follows. In Section 2 we derive our measure of potentiality for a social organization based on the Shannon entropy of a probability distribution. In Section 3 we first explain how this probability distribution can be calculated for a Generalized Hypergeometric Ensemble. The...
The normal distribution is the proper term for a probability bell curve. In a normal distribution, the mean is zero and the standard deviation is 1. It has zero skew and a kurtosis of 3. Normal distributions are symmetrical, but not all symmetrical distributions are normal. ...
In our equation, reliability refers to the probability that the service maintains expected performance standards during its operational state. Reliability can be used as an attribute of availability, describing how well the service performs during transient states of availability and outages as measured ...
