Class-12th CBSE
Subject- Mathematics Set 2
year-2014

Here is some questions:-
1. 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 that both are girls ? Given that
(i) the youngest is a girl.                                       (ii) atleast one is a girl.
2. A card from a pack of 52 playing cards is lost. From the remaining cards of the pack three cards are drawn at random (without replacement) and are found to be all spades. Find the probability of the lost card being a spade.
3. 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.
4. Find the distance between the point (7, 2, 4) and the plane determined by the points A(2,5, -3),8(-2, -3, 5) and C(5, 3, -3).
