Question 975013


I will do A = {M,A,T,H}.


Each letter represents A = {1, 2, 3, 4}. The number of subsets can be calculated as {{{2^4 = 16}}}. All 16 subsets can be written as follows:



P(s) = { }, {M}, {A}, {T}, {H}, {M,A}, {M, T}, {M, H}, {A, T}, {A, H}, {T, H}, 
{M,A, T}, {M,A, H}, {M, T, H}, {A, T, H}, {M,A, T, H}


HINT: For C = {blue, yellow} 


C = {1, 2} and the number of subsets is {{{2^2 = 4}}}. 


Therefore, P(s) = ????



You can do the rest :)
