Question

*If X = {x I x is a prime number , x < 10 } and Y = {y I y is odd number , y <10 } then X∩Y = ?*

1️⃣ {1,3,5,7}
2️⃣ {3,5,7}
3️⃣ {2, 3, 5, 7}
4️⃣ {1,2,3,5,7,9}​

Answer 1

Answer:

Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Answer 2

Solution :-

given that,

→ X = {x I x is a prime number , x < 10 }

So,

→ X = {2, 3, 5, 7}

and,

→ Y = {y I y is odd number , y <10 }

So,

→ Y = {1, 3, 5, 7, 9}

then,

→ X ∩ Y = Set of common elements belongs to both set X and set Y .

therefore,

→ X = {2, 3, 5, 7}

→ Y = {1, 3, 5, 7, 9}

→ X ∩ Y = {3, 5, 7}

Hence, Option (2) {3, 5, 7} is correct answer .
