Answer : (b)
Reason: by the definition of inverse of an implication
|
Answer : (e)
Reason: 26 = 32 so the number of elements in the set are 6.
| |
Answer : (d)
Reason: by the definition of transitive closure
| |
Answer : (b)
Reason: Ceil (3/2) = 2
1/2 + Ceil (3/2) = 2.5
Floor [1/2 + Ceil (3/2)] = Floor [2.5] = 2
| |
Answer : (a)
Reason: by the order of precedence
| |
Answer : (a)
Reason: by the definition of truth tables
| |
Answer : (c)
Reason: all the elements in the set are cubes of first five natural numbers
so The set-builder form of B = {1,8,27,64,125} is {n3 | n∈ N and n≤5}
| |
Answer : (a)
Reason: out of 50 the number of people who do ot watch sprots are 7 so the number of people who watch sports are 43.
people watch both the games = 20+28-43 = 5
| |
Answer : (d)
Reason: by the pigeon hole principle Ceil (110 / 26 ) = Ceil (4.23 ) = 5
| |
Answer : (c)
Reason: by the definition of Non Deterministic Finite State Automata
