Boats use either 1, 2 or 3 signal flags to communicate with other boats (note: a signal with red flag on top and black flag on the bottum has a different meaning than one with black on top and red on the bottum). If there are 10 different colours possible on flags, wha are the total signals possible for a boat to make?

When asked if the sets {azalea, sunflower, orchid, chrysanthemum} and {azalea, orchid, chrysanthemum, sunflower} are equal, Noah responded "No". Explain why you think Noah answered as he did. What is he misunderstanding? Choose the correct answer below. O A. For two sets to be equal, they must contain the same elements without repetition. Since the sets are equal, Noah must have misread the elements in the sets. O B. For two sets to be equal, they must contain the same number of elements. Since the sets are equal, Noah must have miscounted the number of elements in the set. O C. For two sets to be equal, they must both contain exactly the same elements. Since the sets are equal, Noah must misunderstand that the only requirement for sets to be equal is that they contain exactly the same elements. O D. For two sets to be equal, they must contain the same elements in the same order. Since the sets are not equal, Noah is not misunderstanding anything.

Suppose you are going to arrange the following marbles: • blue marble, • red marble, • yellow marble, and green marble. Let's use symbols to represent each marble: • blue marble = b, • red marble = r, • yellow marble =y, and green marble = g. List the different arrangements here:

Solve the problems. draw a Venn diagram to represent the following sets: U= {x|x is a student at ENMU} W= {x|x is a student at ENMU majoring in Computer Science with a minor in Business}   Y= {x|x is a student at ENMU majoring in Computer Science}
