What is the probability of B speaking the truth?

The probability of speaking truth of B, P(B) = 3/4.

What is the probability that they will contradict each other?

The probability that they contradict each other narrating the same incident is. Given that probability that X speaks truth = 60\% = 3/5 . If X speaks truth and the Y speaks false, then X and Y will contradict each other. = 1/2.

In what percent of cases both are speaking truth?

A speaks truth in 80\% cases and B speaks truth in 90\% cases. In what.

What is the probability that an interior point in a circle?

So the favorable outcomes would be the points inside the area of circle with radius r/2, whereas the total possible outcomes would be all the points inside the area of circle with radius r. Therefore the probability is P(E)=πr2πr2/4​=41​

What is the probability of choosing a vowel from the word mathematics?

(a) probability of getting a vowel is 4/11.

What is P A in probability?

So here is the notation for probability: P(A) means “Probability Of Event A” In our marbles example Event A is “get a Blue Marble first” with a probability of 2/5: P(A) = 2/5.

What is the probability of the word Mathematics?

We know that probability of any event is the ratio of the number of favourable outcomes to the total number of possible outcomes. Thus, the probability of getting a letter which doesn’t occur in word MATHEMATICS =1826=913.

What is PA or B?

If events A and B are mutually exclusive, then the probability of A or B is simply: p(A or B) = p(A) + p(B).

What is the probability that A and B speak truth?

A speaks truth in 70\% cases and B in 80\% cases. In what percentage of cases they are likely to contradict each other in giving the same statement. Let the probability that A and B speak truth be P(A) and P(B) respectively.

What is the percentage that A and B will always lie?

What is not entirely clear from the question is whether both A and B will lie in the same way – depending on that, the answer is either 35\% (adding options 2 and 3) or 40\% (adding options 2, 3, and 4). A speaks truth in 80\% cases and B speaks truth in 90\% cases.

What is the probability that the two statements contradict each other?

For the second model, the probability that they contradict each other is the sum of two probabilities, the probability that the first tells the truth and the second lies plus the probability that the first lies and the second tells the truth. That’s 0.75 times 0.20, plus 0.25 times 0.80, which is 0.35.

What is the percentage of a speaking truth and B speaking false?

A speaking truth is 60\% : In that 60\% chance B speaking truth is 70\%. making it overall 42\% (70\% of 60). llly B speaking false is 30\% making it overall 18\%. This is while A speaking truth.
