ii) is a linear homogeneous recurrence relation.
iii) A particular solution of the recurrence relationhas the form
iv) There exists a boolean expression in variables
v) If a dice is rolled thrice, then the probability of getting a 6 each time is
vi) Every odd cycle has the same chromatic and edge chromatic numbers.
vii) Every Eulerian graph is Hamiltonian.
viii) 3 4 S gives the number of ways in which any 3 objects can be placed in any 4 boxes.
ix) There exists a self-complementary planar graph on 5 or more vertices.
x) The number of partitions of 6 is 10.
