2 hunters A & B shot at a bear simultaneously. The bear was shot dead with only one hole in its hide.Probability of A shooting the bear `0.8` & that of B shooting the bear is `0.4.` The hide was sold for Rs. 280/-. If this sum of money is divided between A & B in a fair way, then find their respective shares.

A, B and C try to hit a target simultaneously but independently. Their respective probabilities of hitting the target are 3/4, 1/2 and 5/8 . Find the probability that the target: is hit by exactly one of them.

Three persons A,B and C are taking part in a shooting competition where the person hitting the target first will win Rs 94 probability of hitting by them are 3/5,2/5 and 3/4 respwectively if the cometition is fair and A,B and C shoots in order then calculate the prize money each will win it is given that the total prize money of the competition is Rs 94

An anti-aircraft gun can take a maximum of four shots at an enemy plane moving away from it. The probability of hitting the plane at the first, second, third and fourth shots are 0.4, 0.3, 0.2 and 0.1, respectively, What is the probability that the plane is hit when all the four shots are fired? (A) 0.4379 (B) 0.6872 (C) 0.6976 (D) 0.3507

In a shooting test the probability of A,B,C hitting the targets are (1)/(2),(2)/(3)and(3)/(4) are respectively. If all of them first at the same target. Find the probability that i) Only one of them hits the target, ii) atleast one of them hits the target.

Two particles A and B performing SHM along x and y- axis respectively with equal amplitude and frequency of 2 cm and 1 Hz respectively. Equilibrium positions of the particles A and B are at the co-ordinates (3, 0) and (0, 4) respectively. At t = 0, B is at its equilibrium positions and moving towards the origin, while A is nearest to the origin and moving away from the origin. If the maximum and minimum distances between A and B is s_(1) and s_(2) then find s_(1) + s_(2) (in cm ).

Case Study: The purpose of discipline in the workplace is to input of quality in a timely manner. So, two offices A and B want to award their employees on the values of Honesty, Hard work and Punctuality. Rewarding is a way of motivating one person to perform 'better. The office A wants to award Rs x each, y each and Rs z each for the three respective values to its 3, 2 and 1 employees respectively with a total award money of Rs 2200. Office B wants to spend * Rs 3100 to award its 4, 1 and 3 employees on the respective values (by giving the same award money to the three values as office A). The total amount of award for one prize on each value is Rs 1200. It also serve as a healthy competition between employees for becoming a best asset of the company. Using the concept of matrices and determinants, answer the following questions. The minor of element 6 in the determinant |{:(1,2,3),(4,5,6),(7,8,9):}| is :
