Short Answer

Which projection mapping is used to delete the first, second, and fourth components of a 6-tuple?

The resultant answer is \({P_{3,\;5,\;6}}\).

See the step by step solution

Step by Step Solution

Step 1: Given data

6-tuple is given.

Step 2: Concept of sets

The concept of set is a very basic one.

It is simple; yet, it suffices as the basis on which all abstract notions in mathematics can be built. \(A\) set is determined by its elements.

If \(A\) is a set, write \(x \in A\) to say that \(x\) is an element of \(A\).

Step 3: Simplify the expression

Consider the set of 6-tuple \((A,B,C,D,E,F)\).

If we apply the \({P_{3,\;5,\;6}}\) then we will get the set \((C,E,F)\), which does not contain first, second and fourth component.

Therefore, we apply the \({P_{3,\;5,\;6}}\) to delete first, second and fourth component.
