Q12-B-7 points Find the coefficient of when the following expression is expanded using the Binomial theorem:

A timing diagram is given for inputs to a basic D Flip-Flop. What is the value of the Q output of the D Flip-Flop at time = 1 ns? Assume the delay from inputs changing to output changing is negligible.

Q7-B-8 points A group of 12 students is available. A team of 4 students is to be selected and then arranged in a line for a photo. In how many ways can this be done?

Q3-C 8 points Let ​A​ = {0, 1, 2, 3, 4} and let ​R​ be the relation with digraph with vertex set V and edge set E. Set of Vertices V = {0, 1, 2, 3, 4} Set of Edges E = {(0,0), (1,1), (2,2), (0,4), (4,0), (0,1), (1,0), (1,2), (2,1), (2,3), (3,2), (0,3), (3,0), (1,3), (3,1), (0,2), (2,0)} Note: (2,2) means a loop from the vertex 2 to itself, (2,3) means an edge from vertex 2 to vertex 3, etc, . . .  Test this relation for the following properties: reflexive symmetric transitive
