when an incomplete system fails what is the censoring of this system when a system fails the entire system is censored if one of the components fails the other fails the entire system. what is the pdf of a binary binary what is the pdf of a continuous variable? if an entire manufacturing process fails, rv is not observed how many components are observed if one fails where does a continuous system fail what is the relationship between a continuous variable and a discrete variable? which statement describes the relationship of a continuous and a discrete rv? what is meant by the joint pdf which is a continuous variable what is a joint pdf what is the binary random variable in rv how to derive pdf of an independent variable which type of variable is considered a continuous variable? what if one component fails first what is the joint pdf of a continuous variable and a discrete variable what is the pdf of a continuous variable which variable can only be observed in a manufacturing system
