EGR 1400 EXAM 1 2025 QUESTIONS AND
ANSWERS
In C#, you can simulate rolling two dice by selecting a random number between 1 and 6 to
represent each die roll and then adding them together to get the dice total. Let,s say that we
developed a program to do this and we rolled the pair of dice 50 times and recorded the results
of each roll on a sheet of paper. Can we just select one random number between 2 and 12 and
achieve the same experimental results for the 50 rolls as rolling two die and adding them?
a. No, It's not possible to get the same experimental results with one random number
b. Yes, using the same scaling as before
c. Yes, if the Visual C# code is written to scale the single random number between 2 and 12
d. Yes, if the random number is selected using myRand.Next(2,13); - ANS No, It's not possible
to get the same experimental results with one random number
What property of a Label control would you need to set to change the words displayed in the
