 Hello and welcome to the session. In this session, we will discuss the following question and the question says, write down the following sets in roaster form. Part 1, the set of letters in the word college. Part 2, n belongs to z which is the set of integers such that minus 4 is less than n is less than 2. Part 3, set of multiples of 3 less than 45. Before we start solving the question, let us first recall that is, roaster form of a set in roaster form all the elements are listed and separated by commas and placed within this is. This is a key idea for this question and using this key idea, we will solve the question. Let's start the solution now. Now in part 1, we have the set of letters of the word college. So in part 1, we will first list down the letters of the word college. Now in the word college, the letters are c, o, l, e, g and the repetition of elements is not allowed in the denotation of a set. So each element is written only once. We have to write the set in roaster form and in roaster form all the elements are listed and separated by commas and placed within this is. Now here the letters are c, o, l, e, g. So the given set in roaster form can be written as set a is equal to the set containing the elements c, o, l, e, g. We have listed all the elements within bases separated by commas. So this is our answer for part 1. Now the second part is n belongs to z which is the set of integers such that minus 4 is less than n is less than 2. So in part 2, we have n belongs to z such that minus 4 is less than n is less than 2. So the given set contains all the integers lying between minus 4 and 2. Now the integers are minus 3, minus 2, minus 1, 0, 1. So these are the elements of the set. We will now write the set in roaster form. In roaster form, the set can be written as set b is equal to the set containing minus 3, minus 2, minus 1, 0, 1. This is our answer for part 2. Let's see part 3 now. In part 3, we have set of multiples of 3 less than 35. Now the multiples of 3 less than 35, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, and 42. So these are the elements of the set. And we will write the given set in roaster form. So in roaster form, the set can be written as set c is equal to the set containing the elements 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, and 42. So this is our answer for part 3. With this we end our session. Hope you enjoyed the session. Thank you.
