The probability distribution of a random variable X is given below  A:p (2 ≤ x < 4) B:p(x≥ 4) C p (x ≤ 3) D:p(3≤ x≤ 5) Arrange A, B, C, D in ascending order of magnitude

A random variable X has the probability Distribution  Events E= {X is a prime number} and F= {X / X < 4}


Which of I, II is (are) true

A random variable x has the following probability distribution  Determine P(X > 6)

The range of a random variable X is {0,1, 2} and , P(x = 2)= 5K -1. Then we have

If the range of random variable  and for k =0,1, 2,.....then c =

The range of a random variable X = {1, 2,3, 4,......} and the probabilities are given by , then the value of C is

PQR is a right angled prism with other angles as and . Refractive index of prism is 1.5. PQ has a thin layer of liquid. Light falls normally on the face PR. For total internal reflection, maximum refractive index of liquid is

A point source of light S is placed at the bottom of a vessel containing a liquid of refractive index 5/3. A person is viewing the source from above the surface. There is an opaque disc D of radius 1 cm floating on the surface of the liquid. The centre of the disc lies vertically above the source S. The liquid from the vessel is gradually drained out through a tap. The maximum height of the liquid for which the source cannot be seen at all from above is

A ray of light strikes a plane mirror M at an angle of 45° as shown in the figure. After reflection, the ray passes through a prism of refractive index 1.5 whose apex angle is 4°. The total angle through which the ray is deviated is
