The point (3, 2) undergoes the following three transformations in the order given
(i) Reflection about the line y = x.
(ii) Translation by the distance 1 unit in the positive direction of x-axis.
(iii) Rotation by an angle about the origin in anti-clockwise direction.
Then, the final position of the point is
(- 2, 3)
(0, 3)
Suppose X follows a binomial distribution with parameters n and p, where 0 < p < 1. If is independent of n for every r, then p is equal to
In an entrance test there are multiple choice questions. There are four possible answers to each question, of which one is correct. The probability that a student know the answer to a question is 9/10. If he gets the correct answer to a question, then the probability that he was guessing is
There are four machines and it is known that exactly two of them are faulty. They are teste done by one, in a random order till both the faulty machines are identified. Then, the probability that only two tests are need is
If pth, qth, rth terms of a geometric progression are the positive numbers a, b and c respectively,then the angle· between the vectors (log(a))2i + (log(b))2j + (log(c))2k and (q - r)i + (r - p)j + (p - q)k is
