Question

To reduce controversy and uncertainty on whether there ever was life on planet Fedra, an unmanned experiment is planned. The experiment consists of sending an automatic lab to the surface of Fedra. The lab would conduct chemical and biological tests to reveal whether or not life ever existed on that planet. It is recognized, however, that the experiment may not provide definitive information on the existence of life, due to possible malfunctioning of the testing equipment or the communication system, or the fact that evidence of life may not be present at the locations and depth below the surface accessible by the lab. Let A and B be the events A-"there was life on Fedra", and B ="lab says 'there was life on Fedra". Are A and B mutually exclusive events? Explain your answer as clearly as possible.

Answer 1

event B ="lab says there was life on fedra"

however lab result may not exact due to possible malfunctioning.

mutually exclusive events are those in which two events have no common elements

if lab results are exact then event A and B have common statment.so,

here event A and B are not mutually exclusive
