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?

Given: A 16:1 multiplexer has data inputs D0, D1, …, D15, select inputs S3:0, and output Y.  It is implemented using tristate buffers. What is used to enable the tristate buffer that is connected to D5?

Given: 100101012  is an 8-bit two’s complement number. What is its value in decimal (ex: “-25”, “45”)

Given: A basic 3:8 decoder has address inputs A2:0 and outputs Y0, Y1, …, Y7. Suppose A2 = 0, A1 = 0 and A0 = 1.  Select the correct answer.

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 = 9 ns? Assume the delay from inputs changing to output changing is negligible.

Q5-B-8 points One urn contains two black balls (labeled B1 and B2​) and one white ball.A second urn contains one black ball and two white balls (labeled W1​ and W2​). Suppose the following experiment is performed: One of the two urns is chosen at random. Next, a ball is randomly chosen from the urn. Then a second ball is chosen at random from the same urn without replacing the first ball. a) What is the probability that two balls of different color are chosen? b) Construct the possibility tree with all possible outcomes.
