$L_{1} = a^{m}b^{m}c^{2k} \cup a^{i}b^{j}c^{2k+1}$ The first part is DCFL and the second part is regular. Union of those two becomes DCFL (https://www.geeksforgeeks.org/union-and-intersection-of-regular-languages-with-cfl/). $L_{2} = a^{m}b^{2n}c^{m} \cup a^{i}b^{2n+1}c^{j}$ Same as $L_{1}$, the first part is DCFL, and the second part is regular. Union of those two becomes DCFL. [...]

Firstly, pivot one individual Let X be the number of questions attempted correctly by this person $ E[X] = np = 150 \times \frac{1}{4} = 37.5$ Expected marks = $37.5 – (150-37.5)*0.25$ = 9.375 expected marks will be same for all 1000 students, sum of expected marks will be 1000*9.375 = 9375 Just explaining few more facts about this problems, Number of question attempted correctly by each individual is a binomial’s distribution, (then marks is just a linear function over number of questions attempted, which then again will be binomial) and it is the combination of 150 Bernoulli’s distribution one… [...]

An event is a subset of Universe of sample space (P(U) = 1). Notice here, P(A) = 1, so you can thing of A as whole universe, event B is a subset of event A. $P(A \cap B) = P(B) = \frac{1}{2} $ $P(A/B) = \frac{P(A \cap B)}{P(B)} = \frac{\frac{1}{2}}{\frac{1}{2}} = 1$ $P(B/A) = \frac{P(A \cap B)}{P(A)} = \frac{\frac{1}{2}}{1} = \frac{1}{2}$ [...]

This question certainly needs prior knowledge. It will be very hard to come with the logic in exam. When is a cycle possible in a graph? Whenever there is a back_edge in the DFS traversal of the graph. So how do we avoid it? Convert every edge except the tree_edges as forward_edge. How many can we do a DFS traversal of a complete graph i.e. to fix the direction of tree edges? $n!$ ways. How many ways can we make rest of the edges as forward_edge? Of course only 1 way. Therefore total $n! * 1 = n! \: ways$ to… [...]

All of the girls agree that the first three numbers are 995. Three of them agree that the fourth number is 9. Three agree that the fifth number is 2. Three agree that the sixth number is 6; three others agree that the seventh number is also 6. "Option A" is the best choice because it is made up of the numbers that most of the girls agree they saw. [...]

Correct Answer: (D) Explanation: This game introduces the idea of reciprocal causation. For example, the constraint that says “If A, then B, and if B, then A” should be transcribed in one of the following two ways, based on the configurations of the other variables in the diagram: You will run into reciprocal causation in the final constraint of this logic game. Here are the final diagrams that you should create: Notice how the reciprocal causation constraints are diagrammed. Be aware of the implications of these constraints. For instance, if $B$ is not sent (diagram B), then $A$ cannot… [...]
