Answer And explanation
a)
has 1/
probability guess the correct source
b)
Each element in is mapped by
/
. There are
So there are
-1 elements.
number of target elements =
number of source elements = -1
probability = -1 /
c) Probability of the correct target element
1/
Using the knowledge in computational language in JAVA it is possible to write a code that write a program that reads the width and height of the wall and the number of windows, using the following prompts
<h3>Writting the code:</h3><em>import java.util.Scanner;</em>
<em>public class WallArea {</em>
<em> public static void main(String[] args) {</em>
<em> Scanner sc = new Scanner(System.in);</em>
<em> final int areaOfWindows = 6;</em>
<em> System.out.print("Wall width: ");</em>
<em> double width = sc.nextDouble();</em>
<em> System.out.print("Wall height: ");</em>
<em> double height = sc.nextDouble();</em>
<em> System.out.print("Number of windows: ");</em>
<em> double numberOfWindows = sc.nextDouble();</em>
<em> double area = (width * height) - (numberOfWindows * areaOfWindows);</em>
<em> System.out.println("Area: " + area);</em>
<em> }</em>
<em>}</em>
