One someone has hepatitis b the vaccine for them is of no use True or false?
no
Circular logic would be a statement or series of statements that are true because of another statement, which is true because of the first. For example, statement A is true because statement B is true. Statement B is true because statement A is true
The statement "If A then B" (often written as A → B) means that whenever A is true, B must also be true. However, it does not imply that B is true if A is false; the truth of B is contingent on A being true. In logical terms, the statement is only false if A is true and B is false. Therefore, while A guarantees B, B can still be true independently of A.
The causative agent for Hepatitis B is Hepatitis B virus.
if a is true, then b must be true
Statement: All birds lay eggs. Converse: All animals that lay eggs are birds. Statement is true but the converse statement is not true. Statement: If line A is perpendicular to line B and also to line C, then line B is parallel to line C. Converse: If line A is perpendicular to line B and line B is parallel to line C, then line A is also perpendicular to line C. Statement is true and also converse of statement is true. Statement: If a solid bar A attracts a non-magnet B, then A must be a magnet. Converse: If a magnet A attracts a solid bar B, then B must be non-magnet. Statement is true but converse is not true (oppposite poles of magnets attract).
Yes, the hepatitis B vaccine can be given to someone with hepatitis B. It is still recommended in order to prevent reinfection with other strains of the virus and to protect against potential complications of chronic hepatitis B.
Hepatitis is inflammation in the liver caused by the virus hepatitis B.
The statement you're describing is a form of logical implication often expressed as "If A, then B." In this structure, if A is true, then B must also be true. However, it does not mean that B is always true independently; it is only true when A is true. Therefore, the correct interpretation is that B's truth is contingent upon A being true.
Yes, it is unfortunate true.
not b not a its contrapositive
