## Two events $E$ and $F$ are independent if any one of the following conditions are met: (i) $P\left(E/F\right)=P\left(E\right)$(ii) $P\left(F/E\right)=P\left(F\right)$(iii) $P\left(EnF\right)=P\left(E\right)P\left(F\right)$Is it correct to then assume that if $E$ and $F$ are independent having met condition (i) or (ii), then $E$ and $F$ are also mutually exclusive?

## Flipping a coin we get either head or tail can't get both so events are mutually exclusive. i.e . but flipping the same coin twice may result in either head or tail and result of flipping a coin twice is independent of what appeared the first time. So we can say events are independent?

## A city water supply system involved three pumps, the failure of any one of which crashes the system. The probabilities of failure for each pump in a given year are .025, .034, .02, respectively. Assuming the pumps operate independently of each other, what is the probability that the system does crash during the year?

## Decide whether this statement is true or false: Let $\left(\mathrm{\Omega },\mathbb{F},\mathbb{P}\right)$ be a probability space, if for two events $A,B\in \mathbb{F}$ $\mathbb{P}\left(A\cup B\right)=\mathbb{P}\left(A\right)+\mathbb{P}\left(B\right)$ holds, then $A\cap B=\mathrm{\varnothing }$.

## If are mutually exclusive events, and $P\left(B\right)>0$, show that$P\left(A|A\cup B\right)=\frac{P\left(A\right)}{P\left(A\right)+P\left(B\right)}$My try:1. We know that if are mutually exclusive events, then $P\left(A\cup B\right)=P\left(A\right)+P\left(B\right)$2. We know that $P\left(A|B\right)=\frac{P\left(A\cap B\right)}{P\left(B\right)}$

## Suppose that and $P\left(A\cup B\right)=0.70$. Are A and B mutually exclusive?from what I gather, mutually exclusive events are those that are not dependent upon one another, correct? If that's the case then they are not mutually exclusive since $P\left(A\right)+P\left(B\right)$ does not equal $P\left(A\cup B\right)$. If it was $P\left(A\cup B\right)=0.80$ only then it would have been considered mutually exclusive. Correct?

## Suppose that $A$ & $B$ are mutually exclusive events. Then $P\left(A\right)=.3$ and $P\left(B\right)=.5$. What is the probability that either $A$ or $B$ occurs? $A$ occurs but b doesn't. Both $A$ and $B$ occur.1) Since the are mutually exclusive:$P\left(A\cup B\right)=P\left(A\right)+P\left(B\right)=.3+.5=.8$2) $A$ occurs but $B$ does not: $.3$3) Both $A$ and $B$ occur:Since they are mutually exclusive:$P\left(A\cap B\right)=0$ or the empty setAre these correct?

## What is the probability $P\left(A|A\cup B\right)$ generally for mutually exclusive events $A$ and $B$?Suppose we have mutually exclusive events $A$ and $B$. What would$P\left(A\mid A\cup B\right)$evaluate to? would it be$P\left(A\mid A\cup B\right)=\frac{P\left(A\right)}{P\left(A\cup B\right)}=\frac{P\left(A\right)}{P\left(A\right)+P\left(B\right)}$generally?

## Do mutually exclusive events simply refer to dependent events?To add to the confusion, I also learned that mutually exclusive events can be independent event in a special case when probability is zero i.e. $P\left(A\right)=0$ or $P\left(B\right)=0$ .But an event should either be independent or dependent and not both?

## One way to check whether two events are independent is with the formula $P\left(A\mathrm{&}B\right)=P\left(A\right)\ast P\left(B\right)$. If this holds, the two events are independent (to my knowledge).Now if $A$ and $B$ are mutually exclusive events, and $P\left(A\right)>0$ and $P\left(B\right)>0$, then $P\left(A\mathrm{&}B\right)=0\ne P\left(A\right)\ast P\left(B\right)$, and thus the events are considered dependent. Why does this make intuitive sense?

## If $P\left(A\right)=1/3$ and $P\left({B}^{\complement }\right)=1/4$, then, can $A$ and $B$ be mutually exclusive?

Math can be challenging, but with the right help and understanding, it can be easy to understand. Mutually exclusive events are two events that cannot occur at the same time. If one event occurs, the other cannot. For example, if you are asked a yes or no question, the answer is either yes or no and not both. This concept can be used to solve equations and answer questions. At Plainmath, we understand the difficulty of understanding mutually exclusive events and are here to help. Our website is full of resources, including tutorials and practice questions, to help you understand this concept and any other math questions you may have. Don't wait, get the help you need today!
