A car company get its engines manufactured from three countries A, B, and C. Percentages of engines produced by the three countries A, B, and C are 40%, 35%, and 25% respectively. It is known that 2% of the engines from A, 3 % of the engines from B, and 1% of the engines from C have emission problem (E). Engines are all mixed and in the warehouse. One engine is selected randomly. a) What is the probability that the engine selected has emission problem? b) If the engine does not have emission problem, what is the probability that it came from country B? c) If the engine has emission problem, what is the probability that it was not produced by the country C?

Question
A car company get its engines manufactured from three countries A, B, and C. Percentages of engines produced by the three countries A, B, and C are 40%, 35%, and 25% respectively. It is known that 2% of the engines from A, 3 % of the engines from B, and 1% of the engines from C have emission problem (E). Engines are all mixed and in the warehouse. One engine is selected randomly.
a) What is the probability that the engine selected has emission problem?
b) If the engine does not have emission problem, what is the probability that it came from country B?
c) If the engine has emission problem, what is the probability that it was not produced by the country C?
