Find the probability of the dart hitting the board in the circular region B (i.e. ring B).

Without calculating, write the percentage of probability of the dart hitting the board in circular region C (i.e. ring C).

What is the probability that a randomly thrown dart hits the square board in shaded region (Take π = (22)/(7) and express in percentage)

The probability that A hits a target is 1/3 and the probability that B hits it is 2/5 . What is the probability that the target will be hit if both A and B shoot at it?

A rod of length 'L' is bent in the form a circular loop with a number of turns and is suspended in a magnetic field of intensity B. Find the expression for the maximum torque produced on the circular loop when a current ' I ' is passed through it.

The probability of hitting a target by three marksmen are 1/2, 1/3 and 1/4. Then find the probability that no one will hit the target when they fire simultaneously.

The probability of hitting a target by three marksmen are 1/2, 1/3 and 1/4. Then find the probability that one and only one of them will hit the target when they fire simultaneously.

A wire of length 'I' is bent in the form a circular loop. With a number of turns and is suspended in a magnetic field of intensity B. Find the expression for the maximum torque produced on the circular loop when a current 'I' is passed through it.

The following Venn diagram shows three events, A, B, and C, and also the probabilities of the various intersections. Determine (a) P(A) (b) P(B nn barC) (c ) P(A uu B) (d) P(A nn barB) (e) P(B nn C) (f) Probability of the event that exactly one of A, B, and C occurs.

If A and B are two independent events, the probability that both A and B occur is 1/8 are the probability that neither of them occours is 3/8. Find the probaility of the occurrence of A.
