If `P_(1)`be the probability that a statement made by A is true and `P_(2)` has a similar meaning for B.A and B concur is making a statement S . Find the probability that staement 'S' is true.
A and B are two independent witnesses in a case. The probability that A will speak the truth is x and the probability that B will speak the truth is y. A and B agree on a certain statement. The probability that the statement is true is
A and B are two independent witnesses (i.e., there is no collision between them) in a case. The probability that A will speak the truth is x and the probability that B will speak the truth is y. A and B agree in a certain statement. Show that the probability that the statement is true is (xy)/(1-x-y+2xy).
Identify the true statement (s) .
Probability that A speaks truth is 3/5 , and that for B is 7/10 . If they agree on a statement, then probability that this statement is true is
