P is the set of natural numbers

less than 6.

Therefore,

P = { 1, 2, 3, 4, 5 }

Step-by-step explanation:

Natural numbers:

Natural numbers are those numbers starting from 1, 2, 3, 4, ... and so on.

Also it is denoted by 'N'.

Zero does not include a natural number.

Therefore the set of natural numbers less than 6 is 1, 2, 3, 4, and 5.

Here in the question it is given that

P is the set of natural numbers

less than 6.

∴ P = { 1, 2, 3, 4, 5 }
