 Hello and welcome to the session. In this session we will discuss the following question and the question says write down the following set in set builder form. First part is the set P of months having 30 rays. Second part is the set C of cubes of natural numbers less than 6 and the third part is the set D of numbers that are greater than 2 and less than and equal to 10. Now before we start solving the question let us first review what is set builder form of representing a set. In this form the set is represented as X such that X satisfies the property P within curly braces. Now with this key idea we will solve our question. Let us move on to the solution now. First part says the set P of months having 30 days. Now we know that the months April, June, September and November are the months having 30 days. So the set P will contain the elements April, June, September and November. Now this can be written in set builder form set P is equal to X such that X is a month having 30 days. Let us see the second part now which is set C of cubes of natural numbers less than 6, numbers 1, 8, 27, 64 and 125. But we do not need to put the individual elements in set notation. So in set builder form the set can be represented as set C which is equal to X such that X is equal to n cube where n belongs to set of natural numbers n and n is less than 6 within braces. Now the third part is set D of numbers those are greater than 2 and less than and equal to 10. So here the property that X must satisfy is X is greater than 2 and X is less than or equal to 10. So the set builder form is written as the set D is equal to X such that 2 is less than X is less than or equal to 10 within braces. So this completes our session. Hope you enjoyed the session.
