If E={1,3,5,7,9}, which statement is correct?
Answer and explanation
Correct answer: 7∈E
Set membership is determined by checking whether a number is listed inside the braces. The number 7 appears explicitly in E, so the statement 7∈E is true. Number 5 also appears, making 5∉E false. Numbers 2 and 10 do not appear, so their membership statements are false. Therefore only option C is correct, and the membership symbol is being used appropriately.
