In a large metropolitan area, the probabilities are 0.87,0.36,0.30 that a family (randomly chosen for a sample survey) owns a colour televise set, a black and white television set, or both kinds of sets. What is the probability that a family owns either any one or both kinds of sets?

To solve the problem, we need to find the probability that a randomly chosen family owns either a color television set, a black and white television set, or both. We can denote the events as follows: - Let \( E_1 \) be the event that a family owns a color television set. - Let \( E_2 \) be the event that a family owns a black and white television set. We are given the following probabilities: - \( P(E_1) = 0.87 \) (the probability that a family owns a color television set) ...

One urn contains two black balls (labelled B1 and B2) and one white ball. A second urn contains one black ball and two white balls (labelled W1 and W2). Suppose the following experiment is performed. One of the two urns is chosen at random. Next a ball is randomly chosen from the urn. Then a second ball is chosen at random from the same urn without replacing the first ball. Write the sample space showing aol possible outcomes. What is the probability that two black balls are chosen? What is the probability that two balls of opposite colour are chosen?
