| Re: Maths Previous year Solved Papers
As you are looking for the last year question paper of CBSE XII Maths Exam so here I am sharing the same with you Assume that each born child is equally likely to be a boy or a girl. If a family has.two children, what is the conditional probability if both are girls (i) the youngesr is a girl. :: (ii) atleast one is a girl. A dealer in rural area wishes to purchase a number of sewing machines. He has only < 5,760 to invest and has space for at most 20 items for storage. An electronic sewing machine cost him t 360 and a manually operated sewing machine < 240. He can sell an electronic sewing machine at a profit of 7 22 and a manually operated sewing machine at a profit of 18. Assuming that he can sell all the items that he can buy, how should he invest his money in order to maximize his profit ? Make it as a LPP and solve it graphically. From a lot of 15 bulbs which include 5 defectives, a sample of 4 bulbs is drawn one by one with replacement. Find the probability distribution of number of defective bulbs. Hence find the mean of the distribution.      Rest of the Questions are attached in below file which is free of cost |
