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 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. N u S =

B. Q u W =

C. D u P =
