Let’s assume these are the 25 coins that were collected:
1966 penny, 1967 nickel, 1966 quarter, 1967 penny, 1965 penny, 1966 half dollar, 1967 quarter, 1965 dime, 1967 dime, 1968 quarter, 1964 dime, 1966 nickel,
1965 nickel, 1967 half dollar, 1966 dime, 1964 nickel, 1969 quarter, 1969 half dollar, 1965 half dollar, 1968 penny, 1968 dime, 1964 quarter, 1965 quarter,
1969 dime, 1968 nickel
To simplify writing each coin out, let’s abbreviate 1966 penny by 6P, and 1967 nickel by 7N, etc. So in our collection, we have the following:
6P, 7N, 6Q, 7P, 5P, 6H, 7Q, 5D, 7D, 8Q, 4D, 6N, 5N, 7H, 6D, 4N, 9Q, 9H, 5H, 8P, 8D, 4Q, 5Q, 9D and 8N
A physical model for these coins is found on Material Card 1. If you haven't already done so, cut out a set of coins from this Material Card and use them to do
several of the following exercises.
Let S be the subset of coins from 1964, V from 1965, W from 1966, X from 1967, Y from 1968, Z from 1969 and T from 1970.
Complete the following, using correct notation. List the elements of each set in numerical, then alphabetical order.
a. = {4D,4N,4Q,5N,6N,7N,8N}
b. = {4Q,5Q,6D,6H,6P,6N,6Q,7Q,8Q,9Q}
c. = {4D,5D,5P,6D,6P,7D,7P,8D,8P,9D}

Let be the universal set, where:
Let sets , , and be subsets of , where:
Find the following:
LIST the elements in the set :
= { 1,2,3,4,6,9,10,12,14,15,17,18 }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
LIST the elements in the set :
= { 5,13 }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
LIST the elements in the set :
= { 1,2,3,4,6,7,9,10,12,14,15,16,17,18 }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
LIST the elements in the set :
= { 10 }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
