# Maths - Sets

Write the word or phrase that best completes each statement or answers the question.

List the elements in the set.

1. Let U = { q,r,s,t,u,v,w,x,y,z}

A = { q,s,u,w,y}

B = {q,s,y,z,}

C = { v,w,x,y,z}

a. (A INTERSECT B') U (B INTERSECT A')

B. A'-C

Use the formula for the number of subsets of a set with n elements to solve the problem.

c. A village has 4 fire engines. If a radio dispatcher receives a call, depending on the nature of the situation, no engines , one engine , two engines , three engines , or all four engines can be sent to a fire .
