The answers to the questions are:
a. p = { t, v, c, q}
b. {2, 6} ⊂ {2,6,8,12}
c. {0, 3} ⊄ {3,2,4,6}
To represent sets we use
p = { }
Hence
a. p = { t, v, c, q}
b. If 2 and 6 is a proper subset of [ 2,6,8,12},
This can be represented as
{2, 6} ⊂ {2,6,8,12}
c. the set consisting of the elements 0 and 3 is not a subset of {3,2,4,6} is written as
{0, 3} ⊄ {3,2,4,6}
