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?

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 T.V., a black and white T.V. or both kinds of T.V. The probability that a family own either any one or both kinds of T.V. sets is (i) 0.87 (ii) 0.93 (iii) 0.85 (iv) 0.76

If x represents a number picked at random from the set {-3, -2, -1, 0, 1, 2} , what is the probability that x will satisfy the inequality 4-3xlt6 ?

A matrix is chosen at random from the set of all 2 xx 2 matrices with elements 0 and 1 only. The probability that positive, is

A determinant is chosen at random from the set of all determinant of order 2 with elements 0 or 1 only. Find the probability that the determinant chosen is nonzero.

Two integers x and y are chosen with replacement out of the set {0, 1, 2, . . . 10}. The probability that |x - y| doesn't exceed 5 is

Two integers xa n dy are chosen with replacement out of the set {0,1,,2,3 ,10}dot Then find the probability that |x-y|> 5.

The contents of three urns are as follows: Urn 1-7 white, 3 black balls.Urn 2 - 4 white, 6 black balls Urn 3 - 2 white and 8 black balls.One of these urns is chosen at random with probabilities 0.20, 0.60 and 0.20 respectively. From the chosen urn two balls are drawn at random without replacement. If both these balls are white, what is the probability that these came from urn 3 ?

Two integers xa n dy are chosen with replacement out of the set {0,1,,2,3 ,.....10}dot Then find the probability that |x-y|> 5.

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?

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 all possible outcomes. What is the probability that two black balls are chosen? What is the probability that two balls of opposite colour are chosen?
