Hi! I appreciate your help with the result and approach for these questions. Thanks!

Problem 4(a) 'I point possible (graded, results hidden] Consider a Bernoulli process. with arrival probability at each time slot equal top = lf3. An observer arrives at time slot 10 and sees that no arrival took place in that slot. A passerbv informs the observer that there was exactlyr one arrival during the preceding two time slots ii.e., time slots 8 and 9} but has no additional information about which of the two it was. Let T be the number of time slots starting from the time slot of the last arrival {before slot 10} and until the time slot where the next arrival comes. For example. if the last arrival came at time B and the next arrival comes at time 13, T is the number of slots in the interval {3, 9, 10,11,12, 13}. so that T = 3. {Enter a numerical expression or a decimal accurate to at least 3 decimals places.) Find the probability that T = 4. Smell You have used [I of 3 attempts 53% Problem 4th) 2.0 points possible (graded, results hidden} Continue from and use the same setup as above. Find the expected value of T
