Three LEDs (one red, one green, one blue) turn on when a number 0–7 is passed through. Red turns on with even numbers, green turns on with odd numbers, blue turns on with multiples of 3. Zero means they are all off, seven means they are all on. Set–up the appropriate truth table, simplify using K–maps. Implement, using LogiSim, the simplified logic circuit with optimal number of logic gates.

can someone please explain how to do the logisim?? i am having trouble taking the simplified kmaps answer into logisim

i got everything but the last part

Steps:

Create the truth table using combinational analysis option from window.

click on the inputs menu and provide input variable names and provide output varaible names by clicking on the outputs menu.

Now click on the table menu and change the one's and zero's according to the requirement.

Click on the build circuit and provide a name for the circuit and check the first option to get the circuit in terms of two input basic gates only.

If the circuit is needed in terms of NAND gates only, then provide the second option and click on build the circuit.

If you want to provide the expressions directly,window--->combinational analysis ---->>click on expression and type the expression in the given space directly . Then click on build circuit.

A bag contains one red marble, two blue marbles and three green marbles. A marble is selected at random. Define a random variable X such that X=1 if a red marble is selected, X=2 if a blue marble is selected and X=3 if a green marble is selected. Find the following probabilities. Hint: The blue marbles are different; you can label one blue-1 and the other blue-2. Similarly, each of the green marbles is different. 4a) Find P(X=1) 4b) Find...

There are three types of balls in a box: 5 red, 3 blue and 2 green. You draw 3 balls at once (without replacement) from this box and record: Y1=the # of red balls, Y2=the # of blue balls that you drew. Find the joint probability distribution of Y1, Y2, by first writing the possible values for y1, y2 in rows and columns and then filling in the probabilities within this table. Then check that the sum of the entries...
