Question

Tell whether set A is a subset of set B. Set A: whole numbers less than 10. Set B: whole numbers less than 12

Answer 1

A is a sub set of B if and only if it has the same elements as set B which means that set B is bigger than set B
set A:{1,2,3,4,5,6,7,8,9}
set B:{1,2,3,4,5,6,7,8,9,10,11}
the answer is yes A is a subset of B
