Answer: d. should be lowercase.
Explanation:
ID attributes are case sensitive for the most part - DOM and Java Script - which means that the ID attribute does not always have to be lowercase.
It can be uppercase as well. ID attributes can also start with a number and as of HTML 5 can start with a special character as well. Finally, the ID attribute must always be unique within each document.
Answer: D) Whitelisting
Explanation:
Whitelisting are used in many applications and it only allows the good known apps. Whitelisting are majorly used for security purpose as, it permits to maintain or control the misuse the apps by employees in an organisation.
Blacklisting maintain the list of denied access system and it prevented the accessing undesirable program. It is also used as security application but it is less effective than whitelisting.
Encryption are the process which are not used in the restricting application. And lockout are used by the users for entering the password for many time as possible.
Therefore, option (A) is correct.
Answer:
5/ 18
Explanation:
Given :
List A: [20,10,20]
List B: [40,10,30,20,40,30]
Chance that number drawn from list A is larger than or equal to that drawn dlfrom list B.
If:
A = 20
B ≤ 20 : [10,20] = 2
A = 10
B ≤ 10 : [10] = 1
A = 20
B ≤ 20 : [10,20] = 2
Probability = Required outcome / Total possible outcomes
Hence,
required outcome = (2 + 2 +1) = 5
Total possible outcomes = 3C1 * 6C1 = (3 * 6) = 18
Hence,
chance that the number we drew from list A is larger than or equal to the number we drew from list B
= 5 / 18
