Question

{2, 2, 4} _____ {1, 2, 3, 4, 5} Make correct statement by filling in the symbols $\subset or \not \subset$. in the blank space.

Answer 1

we know, A set is known as subset of another set if all elements of the set are elements of the set. for example :- set A = {a, e, i} and set B = {a, b, c , d , e , f , g , h , i} are given then, we can say set A is subset of set B, because all elements of set A are elements of set B.
hence, we can write it $A\subset B$

here, Let A = {2, 3, 4} and B = {1, 2, 3, 4, 5}
all elements of set A are elements of set B.
so, $\bf{A\subset B}$
