A : It is important to introduce data representation and analysis in the primary stage and to strengthen it in the upper primary stage.
B : Data analysis exposes children at primary level to uncertainty and changeability in information as opposed to the fixed nature of mathematical facts they mostly study.
Choose the correct option.
Assertion (A) states the importance of introducing data representation and data analysis at the primary stage and strengthening it in the upper primary stage.
Reason (B) explains that data analysis exposes children to uncertainty and changeability in information, contrasting it with the fixed nature of typical mathematical facts.
The question asks if Reason (B) correctly explains why Assertion (A) is important.
Both Assertion (A) and Reason (B) are true, and Reason (B) correctly explains Assertion (A).
The correct option is the one that reflects this: A is true and B is the correct reason of A.
The cost of a machine is Rs. 20,000 and its estimated useful life is 10 years. The scrap value of the machine, when its value depriciates at 10% p.a, is:

Let C be the circle of radius π/4, centered at z = \(\frac{1}{4}\) in the complex z-plane that is traversed counter-clockwise. The value of the contour integral ∮c\(\frac{{{{\rm{z}}^{\rm{2}}}}}{{{\rm{si}}{{\rm{n}}^{\rm{2}}}{\rm{4z}}}}\)dz is
Let X be a real-valued random variable such that E[eX] < ∞ and E[eX] = eE[X]. Then which of the following is correct?
There are three urns U1, U2, U3, each with balls of two colours. U1 contains 2 white balls and 3 black balls, U2 contains 3 white balls and 2 black balls and U3 contains 5 white balls and 5 black balls. An urn is chosen at random and a ball is drawn from that urn at random. What is the probability that U2 was chosen given that the ball picked is black in colour?
Let {Xn ∶ n ≥ 0} be a two state Markov chain with state space S = {0, 1} and transition matrix
