Which of the following is the set A = {x : x is an odd natural number from 1 to 10}?
Answer and explanation
Correct answer: A = {1, 3, 5, 7, 9}
The odd natural numbers in the inclusive interval from 1 through 10 are numbers that are not divisible by 2: 1, 3, 5, 7, and 9. The number 10 is even, and 11 lies outside the stated interval. Hence the roster form of the set is A = {1, 3, 5, 7, 9}, so option A is correct.
