A man is known to speak truth 3 out of 4 times. He throws a die and reports that it is a six. Find the probability that it is actually a six.

Probability that A speaks truth is 4/5 . A coin tossed. A reports that a head appears. The probability that actually there was head is a) 4/5 b) 1/2 c) 1/5 d) 2/5

A bag contains 5 red balls, 3 black balls and 4 white balls. A ball is drawn out of the bag at random What is the probability that the ball drawn is white? Hence find the probability that the ball drawn is either red or white. find the probability that the ball drawn is either red or black.

A bag contains 5 red balls, 3 black balls and 4 white balls. A ball is drawn out of the bag at random What is the probability that the ball drawn is white? Hence find the probability that the ball drawn is either red or white

A can hit target 4 times out of 5 times,B can hit target 3 times out of 4 times and C can hit target 2 times out of 3 times. They fire simultaneously.Find the Probability that None of them will hit the target.

The probability that a student passes in a physics test is 2/3 and the probability that he passes both the physics and English test is 14/45 . If the probability that he passes at least one test is 4/5 , find the probability that the student passes exactly one of the two tests

An experiments succeeds twice as often as it fails.Find the probability that in the next six trials,there will be atleast 4 successes.

A can hit target 4 times out of 5 times,B can hit target 3 times out of 4 times and C can hit target 2 times out of 3 times. They fire simultaneously.Find the Probability Any two out of A,B and C will hit the target.

The probability that a student passes in a physics test is 2/3 and the probability that he passes both the physics and English test is 14/45 . If the probability that he passes at least one test is 4/5 , find the probability that the student passes neither the Physics test nor the English test.
