Question 202082
Recall that the number of subsets of a set with "n" elements is {{{2^n}}}. In this case, there are 4 elements. So the number of subsets is {{{2^4=16}}}



So the answer is D) 16



Here are the list of all the possible subsets (count them and you'll find that there are 16 subsets)



{mom, dad, son, daughter},
{mom,dad,son}, {mom,dad,daughter}, {mom,son,daughter}, {dad,son,daughter},
{mom, dad}, {mom, son}, {mom, daughter}, {dad, son}, {dad, daughter}, {son, daughter},
{mom}, {dad}, {son}, {daughter},
{}


Note: {} is the empty set
