Answer:

7

Step-by-step explanation:

The cardinality of a set is the number of elements in the set

Given the set W = x is a day of the week

The days of the week are {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday}

Hence the set W will be;

W = {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday}

n(W) = 7 (since there are 7 days in a week)

Hence the cardinality of the set W is 7
