Using the Venn diagram, find 𝑈 minus 𝑋 prime.
We can see from the Venn diagram that 𝑈 is the set of the four numbers two, six, seven, and nine. The set 𝑋 contains the numbers inside the circle, seven and nine. The notation 𝑋 prime or 𝑋 bar means the complement of 𝑋. This is all the values that are not contained in 𝑋.
In this question, 𝑋 prime or the complement of 𝑋 contains the values two and six. These are the two numbers that are not in set 𝑋. We need to subtract the complement of 𝑋 from 𝑈. Removing two and six from 𝑈 leaves us with two numbers, seven and nine. 𝑈 minus 𝑋 prime leaves us with set 𝑋, the numbers seven and nine.
