Table Creation: Creating table comes under Data Definition Language (DDL). Syntax for creating table is as follows: CREATE TABLE TABLE_NAME ( Column1 datatype, Column2 datatype, … ); ALTER TABLE Statement: “ALTER TALE” statement comes under Data Definition Language. It is used to modify column, add constraints, add column(s), drop column, rename column name and table name, drop constraints, and so on. Syntax: Syntax to drop constraint is as follows: ALTER TABLE table_Name DROP CONSTRAINT constraintName;

Question

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?
