The hazard that John watch outes a certain television verbalise is .4. The fortune that Jane watches the direct is .5. The f ortune that John watches the show, given that Jane does is .7. a come up the probability that both John and Jane watches the show P(John | Jane) * P(Jane)=P(John and Jane)/P(Jane) =(0.7)×(0.5)=0.35 b Find the probability that Jane watches the show, given that John does. P(Jane | John)=P(Jane and John)/P(John)=(0.35)/(0.4)=0.875 c Do John and Jane watch the show one by one of each otherwise?

rationalize jour answer. P(Jane) * P(John) = (0.5) * (0.4) = 0.20 P(Jane and John) ? P(Jane) * P(John) = 0.35 ? 0.20 This means that they dont watch the show independently of each other. 5.12 Suppose the probability distribution of a haphazard variable x can ! be describe by the formula p(x) = X/15. for each of the values x - 1, 2,3,4 and 5. face P(x+2) = p(2) =p(2) =2/15. a. Write out the probability distribution of x x| P(x)=x/15| X*p(x)| (x^2) * P(x)| 1| 0.0667| 0.0667| 0.0667| 2| 0.1333| 0.2667| 0.5333| 3| 0.2000| 0.6000| 1.8000| 4| 0.2667| 1.0667| 4.2667| 5| 0.3333| 1.6667| 8.3333| b. Show that the probability distribution of x...If you regard to get a full essay, narrate it on our website: BestEssayCheap.com
