Two-dimensional array: • A two-dimensional array is also referred as 2D arrays which can store multiple collections of data. • It contains the rows and columns of elements. • In two-dimensional array, normally the first subscript is called as row size and the second subscript is called as column size. • All the rows will have equal number of columns. So, the arrangement of array elements looks like rectangular structure. Declaration of two-dimensional array: The two size declarators are needed to declare the two-dimensional array. • First indicates the number of rows. • Second indicates the number of columns. The syntax to declare the two-dimensional array is given below: datatype[,] arrName = new datatype[rows, columns]; Where, • “datatype” indicates the data type of variable. • “arrName” indicates the name of two-dimensional array variable. • “rows” indicates the number of rows. • “columns” indicates the number of columns.

Program Plan Intro

Two-dimensional array:

• A two-dimensional array is also referred as 2D arrays which can store multiple collections of data.

• It contains the rows and columns of elements.

• In two-dimensional array, normally the first subscript is called as row size and the second subscript is called as column size.

• All the rows will have equal number of columns. So, the arrangement of array elements looks like rectangular structure.

Declaration of two-dimensional array:

The two size declarators are needed to declare the two-dimensional array.

• First indicates the number of rows.

• Second indicates the number of columns.

The syntax to declare the two-dimensional array is given below:

datatype[,] arrName = new datatype[rows, columns];

Where,

• “datatype” indicates the data type of variable.

• “arrName” indicates the name of two-dimensional array variable.

• “rows” indicates the number of rows.

• “columns” indicates the number of columns.

My daughter is a Girl Scout and it is time for our cookie sales. There are 15 neighbors nearby and she plans to visit every neighbor this evening. There is a 40% likelihood that someone will be home. If someone is home, there is an 85% likelihood that person will make a purchase. If a purchase is made, the revenue generated from the sale follows the Normal distribution with mean $18 and standard deviation $5. Using @RISK, simulate our door-to-door sales using at least 1000 iterations and report the expected revenue, the maximum revenue, and the average number of purchasers. What is the probability that the revenue will be greater than $120?
