Question

X= { xlx is a prime number between 80 and 100}
Y = { yly is an odd number between 90 and 100},then find set x,set y , x n y ,x u y.​

Answer 1

Answer:

X= {83, 89, 97}

Y= {91, 93, 95, 97, 99}

X u Y = {83, 89, 91, 93, 95, 97, 99}

X n Y = {97}

Step-by-step explanation:

X u Y (or) X union Y means we take all the numbers in both sets (no repetitions). If either X or Y is not a null set then this operation will never result in a null set.

X n Y (or) X intersection Y means we take only the common numbers contained in both sets. The operation may result a null set if no common number exists between the two.
