Question

If X and Y are two sets such that n (X) = 17, n (Y) = 23 and n (XUY) = 38, find n (XY)​

Answer 1

Step-by-step explanation:

17 x 23 =391

391 is the answer may it helps

Answer 2

Answer:

We can use the formula for the size of the union of two sets:

n(X U Y) = n(X) + n(Y) - n(XY)

Substituting the given values, we get:

38 = 17 + 23 - n(XY)

Simplifying, we get:

n(XY) = 17 + 23 - 38

n(XY) = 2

Therefore, the size of the intersection of sets X and Y is 2.
