Intermediate Mathematics - Relationship between hypergeometric and
Relationship between the hypergeometric and binomial distributions
A production line produces lithium batteries for use in mobile phones. In
every 1000 batteries, there are known to be eight batteries which don't
work. A sampling process, to check the number of non-working batteries, is
conducted for every 1000 batteries produced. This sampling process randomly
selects five batteries from the production line and the number of
non-working batteries is noted.
Find the probability of choosing three non-working batteries in this
sample of five batteries.
