In a lot of 6 batteries, one is worn out, this is unknown to the technician and technician tests
the batteries one at a time until the worn-out battery is found. Tested batteries are put aside, but
after every 3
rd test the tester takes a break and another worker, unaware of the test, returns one of
the tested batteries to the set of batteries not yet tested.
Find probability distribution function (pdf) of X, the number of tests required to identify the
worn out battery.
