Question
Engineering company has a task of
checking compressive strength for
100 concrete cubes. The results
revealed that 85 cubes passed the
compressive strength test
successfully and 15 cubes failed in
the test. If 10 cubes are selected at
random to be inspected by the
company, determine the probability
that the 8 cubes will pass the test
and 2 cubes will fail in the test by
using the Combinatorial Analysis.
