UGC net July 2018 Q84
Digital data received from a sensor can fill up 0 to 32 buffers. Let the sample space be S={0, 1, 2, â€¦â€¦â€¦., 32} where the sample j denote that j of the buffers are full and p(i) = 1 / 566 *(33 â€“ i). Let A denote the event that the even number of buffers are full. Then p(A) is: (A) 0.515 (B) 0.785 (C) 0.758 (D) 0.485
