Question

which of the following is not an empty set? A. {vowels in the word rhythm} B. {day in a week that starts with the letter J} C. {bicycle with four wheels} D. {soldiers in the philippines}​

Answer 1

B. {day in a week that starts with the letter J}

Explanation:

In the given situation if we go option B that the day in the week started from the letter J

So if we write the total days in a week i.e.

Monday, Tuesday, wednesday, thursday and friday

Now as we can see that there is no day in a week started with J letter

So the option b is correct
