The probability that a contractor will get a plumbing contract is 2/3 and the probability that he will not get an electric contract is 5/9. The probability that he will get at least one contract is 4/5.suppose A is the event that ther contract will get plumbing contract and B is the event that the contractor will get electric contract.Also find the probability that the contractor will get both the contracts.

The probability that a contractor will get a plumbing contract is 2/3 and the probability that he will not get an electric contract is 5/9 . The probability that he will get at least one contract is 4/5 .suppose A is the event that the contractor will get plumbing contract and B is the event that the contractor will get electric contract. using addition theorem of probability find the probability that the contractor will get both the contracts.
