Answer 1

Given:

Set: x | x is a day of the week starts with letter j.

To find:

We need to find the number of elements in the given set.

Solution:

According to the question, x | x is a day of the week starts with letter j.

Before solving the question, we should know the names of days present in a week.

We know that, in a week, there are 7 days.

• 1st day of the week is Monday.
• 2nd day of the week is Tuesday.
• 3rd day of the week is Wednesday.
• 4th day of the week is Thursday.
• 5th day of the week is Friday.
• 6th day of the week is Saturday.
• 7th day of the week is Sunday.

If we observe the days of the week, it is clear that, none of the day starts with the letter j. So, the given set does not contain any days.

Therefore, there are no elements for the given set.
