Please describe the steps of the problem in as much detail as
possible, will rate. Thank you.
Problem 7 (Blitzstein and Hwang, Problem 44) Let A1, A2,..., An be events. Let Bk be the event exactly k of the A; occur, and Ck be the event that at least k of the A; occur, for 0 < k < n. Find a simple expression for P(Bk) in terms of P(Ck) and P(Ck+1).
Please help me solve the following problem. please write neatly.
Consider randomly selecting a student at a certain university, and let A denote the event that the selected individual has a Visa credit card and B be the analogous event for a MasterCard where PCA) - 0.55, PCB) = 0.45, and PCA n B) -0.20. Calculate and interpret each of the following probabilities (a Venn diagram might help). (Round your answers to four decimal places.) (a) P(BIA) (b) P(8' )...

2. Lower back pain is a common complaint that is hard to treat effectively. Does regular physical therapy help? A randomized experiment assigned patients visiting their doctor for lower back pain to two groups: 142 received an examination and advice from a physical therapist; another 144 received regular physical therapy for up to five weeks. After a year the change in their level of disability (0%...
Please show also the work. Thank you.
(after a Stallings problem) Assume at time 5, no system resources are being used except the processor and memory. Given this, consider this sequence of events: at time = 5: P1 executes a command to read from disk unit 3; at time = 15: P5's time slice expires; at time = 18: P7 executes a command to write to disk unit 3; at time = 20: P3 executes a command to read from...
please also include the explanations and write in
paper. thank you
