A manufacturing item exhibits two types of faults, say ???? and ????, which occur independently of one another. The probability of a fault, which is type-????, is 12%, while a type-???? fault has a probability of 16% of occurring. Find the probability

(i) that an item has both types of faults;

(ii) that an item has at least one type of these faults;

(iii) that the item has a fault which is of type-????, if we know that it also has a fault which is type-????.
