Answer:

True

Explanation:

Main functions of operating systems are

To provide user interface

To manage resources

To run applications

"An operating system is the most important software that runs on a computer. It manages the computer's memory and processes [resources], as well as all of its software and hardware [like running applications]. It also allows you to communicate with the computer without knowing how to speak the computer's language [interface]. Without an operating system, a computer is useless."

Mariana [72]

Answer:

Following are the solution to the given question:

Explanation:

Please find the complete and correct question in the attachment file.  

For Point a:

For the second round,

A is selects kA(2)  either 0 or 1, so for each of them, that is \frac{1}{2}.

B selects kB(2)\  from\  (0, 1, 2, 3) for each choice with the probability of \frac{1}{4}.

If kA(2) < kB(2) wins the second rear race.

\to P[A \ wins] = P[kA(2) < kB(2)]

                     = P[kA(2) = 0] \times P[kB(2) > 0] + P[kA(2) = 1] \times P[kB(2) > 1]\\\\= \frac{1}{2} \times \frac{3}{4}  + \frac{1}{2}  \times \frac{2}{4} \\\\=\frac{3}{8}  +\frac{2}{8} \\\\= \frac{3+2}{8}\\\\= \frac{5}{8}

For Point b:

Throughout this example, kA(3) also selects to be either 0 or 1 with such a \frac{1}{2} probability. So, although B chooses kB(3) from (0, 1, 2, 3, 4, 5, 6, 7), the probabilities each are \frac{1}{8}:

\to P[A \  wins] = P[kA(3) < kB(3)]

                     = P[kA(3) = 0] \times P[kB(3) > 0] + P[kA(3) = 1] \times P[kB(3) > 1]\\\\= \frac{1}{2} \times \frac{7}{8} + \frac{1}{2} \times \frac{6}{8}\\\\= \frac{7}{16} + \frac{6}{16}\\\\= \frac{7+6}{16} \\\\= \frac{13}{16}\\\\

For point c:

Assume that B tries again 16 times (typical value), and it destroys. In addition, throughout the exponential background n is obtained at 10 when choosing k between 0 to 2n−1. The probability of A winning all 13 backoff events is: P[A \text{wins remaining races}] = 16\pi i =4P[A \ wins \ i |A \ wins \ i -1 ]

Let the k value kA(i) be A for the backoff race I select. Because A retains the breed

=(kA(i)] \cdot P[kA(i+ 1)< kB(i+ 1)] \geq P[kA(i) + 1

For point d:

Two stations A and B are supposed. They assume that B will try 16 times afterward. Even so, for A, 16 races were likely to also be won at a rate of 0.82 For Just higher expectations of three A, B, and C stations. For Station A, possibility to win all backoffs

What's wrong with my program? Here is my code , if the user wants a 3rd card dealt they, have to select yes and the total will b
Mashcka [7]

Your issue is on line 19 in your if statement. In python, if you have more than one condition in an if statement, you have to explicitly mention it after the or.

Your if statement is

if again == "Y" or "y":

However, this will always return true because the second statement simply asks "y".

To correct this, simply change the if statement to:

if again == "Y" or again == "y":

This will correct your code.

Another thing to consider is to always convert a userinput (whenever possible) to one version, this can be accomplished in your code by converting "again" into one version by using the .lower function.

again = input("Would you like to draw a 3rd card? Y or N? ")

again = again.lower()

Hope this helps!
