Solution
Sure, here are the answers to your questions:
-
A - B is the set of elements that are in A but not in B. Since all elements of A are also in B, A - B is an empty set. So, the answer is 4) .
-
A relation R on a set A is called a partial order if it is reflexive, anti-symmetric, and transitive. So, the answer is 3) Reflexive, Anti-Symmetric and Transitive relation.
-
If A and B are two independent events, the probability of A union B is equal to the sum of the probabilities of A and B. Given that P(A) = 0.5 and P(A U B) = 0.8, we can find P(B) by subtracting P(A) from P(A U B). So, P(B) = P(A U B) - P(A) = 0.8 - 0.5 = 0.3. None of the provided options match this result.
-
A context-free grammar G is ambiguous if there is some string w that belongs to L(G) that has two distinct parse trees. So, the answer is 2) Parse trees.
