Elizabeth wanted to know the gender and the hair color of each of her classmates. She arranged the results of this survey into a two-way table, shown below. According to the table, what is the marginal relative frequency of students in the class that have blonde hair?
Joint, Marginal & Conditional Frequencies | Definition & Overview from Chapter 3 / Lesson 13 305K Learn the joint, marginal, and conditional relative frequency definitions and see how to identify each in a two-way table. Study examples of e...
The joint probability mass function p(x,y) is defined for each pair of numbers (x,y) by p(x,y)=P(X=x and Y=y). It must be the case that p(x,y)⩾0 and ∑x∑yp(x,y)=1.The marginal distribution of a subset of a collection of random variables is the probability ...
Isn't it also a problem if just one of the conditional distributions assigns zero probability to some region where the corresponding marginal has nonzero probability? If just one of [tex]p(a)[/tex] and [tex]p(b)[/tex] is zero, one can just invert both sides of [tex]\frac{p(a)...

If the joint probability function of variables is given, then we can find conditional probabilities using them. If conditional probabilities and marginal probabilities are given, we can use them to find the joint probability.Answer and Explanation: ...
Hey, I have a really simple question. How can I obtain a marginal density fx(x) from a joint distribution (x,y) ? In my case the joint distribution follows a log-normal distribution. I cannot use Quad since it requires both integrals (x and y). Thanks a lot for your help. Mo...
