a. A u B u C:
To find the elements of A u B u C, we need to combine the elements from sets A, B, and C without duplication.
Elements of set A: {10, 15, 20, 25, 30}
Elements of set B: {11, 13, 17, 19, 23, 29}
Elements of set C: {11, 13, 15, 17, 19, 21, 23, 25, 27, 29}
Combining all the elements without duplication, we get:
{10, 11, 13, 15, 17, 19, 20, 21, 23, 25, 27, 29, 30}
b. A u B n C:
To find the elements of A u B n C, we need to combine the elements of sets A and B, while including only the elements that are also in set C.
Elements of set A: {10, 15, 20, 25, 30}
Elements of set B: {11, 13, 17, 19, 23, 29}
Elements of set C: {11, 13, 15, 17, 19, 21, 23, 25, 27, 29}
Finding the common elements in A, B, and C, we get:
{15, 17, 19, 23, 25, 29}
c. A' n B n C:
To find the elements of A' n B n C, we need to find the elements that are not in set A, but are present in both sets B and C.
Elements of set A: {10, 15, 20, 25, 30}
Elements of set B: {11, 13, 17, 19, 23, 29}
Elements of set C: {11, 13, 15, 17, 19, 21, 23, 25, 27, 29}
Finding the elements not in A, but present in B and C, we get:
{11, 13, 17, 19, 23, 29}
Given that €={10,11,12,13,14,15......,30}
A= {Multiples of 5}
B={prime number of 10,11,12,13,14,15...,30}
C={odd number}
Find the element of:
a. A u B u C
b. A u B n C
c. A' n B n C
