Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )

Remember, Hard = Physical.
If that's not it, try peripherals.
It is true. RDBMS enforce integrity rules automatically. Integrity rules are automatically enforced by RDBMSs.
Integrity rules are automatically enforced by RDBMSs. Because it contains the design choices made regarding tables and their structures, a data dictionary is frequently referred to as "the database designer's database." Any character or symbol intended for mathematical manipulation may be contained in character data.
Data points that are connected to one another are stored and accessible in a relational database, which is a form of database. The relational model, an easy-to-understand method of representing data in tables, is the foundation of RDBMS. Each table row in a relational database is a record with a distinct ID known as the key.
It is simple to determine the associations between data points because the table's columns carry the properties of the data and each record typically has a value for each property.
