However, it is not known whether burstiness is an epiphenomenon of human-specific patterns of communication. Burstiness has been cited as a possible cause for slow spreading in these networks relative to a randomized reference network. Heavy-tailed (bursty) time distributions are characteristic of human communication networks, including face-to-face contacts and electronic communication via mobile phone calls, email, and internet communities. The dynamics of spreading depends, among other factors, on the distribution of times between successive contacts in the network. This is $60\%$ of $80\%$.Social networks mediate the spread of information and disease. The total proportion of people who pass practical exam will be $0.8\cdot 0.6=0.48$ or $48\%$. And $0\%$ will pass practice among those people who did not pass theoretical exam. You can see that $60\%$ refers only to those people who pass the theoretical exam. Among these people $60\%$ will pass a practical exam. $T$ is a part of those people who will pass theoretical exam ($80\%$). In order to understand the relations of this events and probabilities correctly, It is convenient to imagine a lot of people ($100\%$) going to take exams for a driver's license. The unconditional probability that the practice test will be passed by some individual The probability of both events $T$ and $P$ occured is the product of probability of the first one and the conditional probability of the second one if the first occured. $\mathcal A\quad$ The self-assessment grid tells me that the answer is $0,48$Īt first I tried to no overthink it and went like this: let ($*$ translation, emphasis and bold are mine)
$\mathcal Q\quad$ What is the probability of successfully pass the driving test? The probability to pass the theory test is $0.8$ the probability to pass the practice test is $0.6$.
To do the practice test you have to pass the theory test. There are two parts in a driving test: a theory test and a I checked the self-assessment grid and then went back to my textbook avoiding wikipedia or more advanced material on purpose in order to understand exactly what they expect me to answer with the knowledge they assume I have (math exam IV° EU level if can be of any help). I was doing a math exam simulation and I found a problem on probability that I can't understand.
