They require to write a Boolean of power 4, but what if the number of elements is more, to truncate the elements in the set?

Question

Mathematics

If we are required to write sets Z of cardinality 4, should we cut our set down to 4 elements? because in my case, the set Z can consist of 7 elements
Z = {1,2,3,4,5,6,7}

Answer 1

Read the question more carefully:
So you can safely take any 4 elements of the set Z and work with them.
PS Understanding the condition of the problem is already half the solution to the problem, so I recommend paying attention to every word of any mathematical problem.
