In a laboratory, there are two types of tests done for a concrete cubes: compression strength test and water absorption test .25% failed in compression test. 40% passed in water absorption test and 15% failed in both. Find: 1) Probability that a random sample selected is bad in compression test and good in absorption test. 2) Probability that a random sample selected is bad in absorption test and good in compression test. 3) The probability that a random sample selected is good in both test. 4) The probability that a random sample selected at least one of them is bad.
