The formula for conditional probability is: P(B|A) = P(A and B) / P(A) which you can also rewrite as: P(B|A) = P(A∩B) / P(A) Need helpwith homework?Check out our tutoring page! Conditional Probability Formula
3votes Accepted What is meant by "When we construct conditional probabilities, the relative proportions of probabilities remain the same."? As @Sextus Empiricus mentioned in a comment, when A and C both imply B, then the statement is true: IfA⊂BA⊂BandC⊂BC⊂B, then $$\frac{P(A...
Spoiler Alert: Calculate each probability before checking your answers below. The probability that a randomly-chosen card is a heart is 13 out of 52, or 25%. If we know that the card is red, that probability is doubled to 13 out of 26, or 50%. ...
Explain the following concepts in probability and provide examples for each: 1. Independent vs Dependent Events 2. Mutually-exclusive Events 3. Conditional Probability. The probability of A or B is 0.8 , i.e, P ( A or B ) = P(A \cup B) = 0.8 . The probability of B is 0.3 . Wha...

We give examples to show that previous attempts to solve the two problems, using probabilistic logic and similar methods, can produce incorrect answers. Using ideas from the theory of imprecise probability, we show that the general problems have simple, direct solutions which can be implemented ...
Let's do a few more examples together just to make sure you've got it. If I run out of butter, I'll just use oil.让我们一起看看更多的例子，保证你已经完全掌握了吧。如果黄油用完了，我就会用油。So again imagine, imagine that you're baking and there isn't much butter left. You can...

Since the nonmonotonicity phenomenon was already well known in probability theory — a conditional probability P(Y|X) being high does not entail the conditional probability P(Y |X∩ Z) being high — it is not surprising that some of the modern accounts of nonmonotonic conditionals turn out to...
I already fitted the best copula function to my variables (let's say X and Y). Now, I have the CDF and PDF of best copula. What I want to do is to find out the conditional probability of this joint distribution based on exceedance from X and non-excee...
