Two types of defects are observed in the production of integrated circuit boards. It is estimated that 6% of the boards have solder defects and 3% have some surface-finish defects. The occurrences of the two types of defects are assumed to be independent of each other.
If a circuit board is randomly selected from the output, find the probabilities for the following situations:
(a) Either a solder defect or a surface-finish defect or both are found.
(b) Only a solder defect is found.
(c) Both types of defects are found.
(d) The board is free of defects.
(e) If a surface-finish defect is found, what are the chances of also finding a solder defect?
