Consider the set A of binary strings of length five. Examples are 00000, 01000, 10010, etc. Let B be a subset of A where the binary strings in B all have an even number of 1's. Let C be a subset of A where the binary stings in C start and end with 1's. Let D be a subset of A where the binary strings in D have exactly 4 1's. What is the size of BU CUD? O 17 O 21 O 20 O 29
