Asystem consists of two identical pumps, #1 and #2. if one pump fails, the system will still operate. however, because of the added strain, the remaining pump is now more likely to fail than was originally the case. that is, r = p(#2 fails | #1 fails) > p(#2 fails) = q. if at least one pump fails by the end of the pump design life in 8% of all systems and both pumps fail during that period in only 4%, what is the probability that pump #1 will fail during the pump design life?

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
