Question

if W={u,v,w,x,y,z},X={13,15,17,19,21},then find:1)n(W) 2)n(X) 3) Is n(W)=n(W)?​

Answer 1

Step-by-step explanation:

n(W)=6

n(X)=5

n(W) is not equal to n(X)

Answer 2

Given:

W={u,v,w,x,y,z }, X= { 13,15,17,19,21},

To find:

i) n(W) ii)n(X). iii) Is n(W)= n(X)?

Solution:

i) n(w)

W={u,v,w,x,y,z },

In order to find the n(w), we need to count the elements of the given set. There are 6 elements.

=> n(w) = 6

ii)n(x)

X= { 13,15,17,19,21},

In order to find the n(x), we need to count the elements of the given set. There are 5 elements.

=> n(x) = 5

iii) Is n(W)= n(X)?

n(w) = 6 and n(x) = 5

we can see that the elements in both the sets are not equal. So, n(W) $\neq$ n(X)
