Question
The probability that the first record of a singing group will be a hit is 0.48. If their first record is a hit, so are all their subsequent records. If their first record is not a hit, the
probability of their second and all subsequent ones being hits is 0.24. If the first two records are not hits, the probability that the third is a hit is 0.12. Find the probability that
a group has exactly 2 hits in their first three records.
P(exactly 2 hits in first three records) =
(Simplify your answer. Type an integer or a decimal. Round to 6 places.)
