Question

Let U = {English, French, History, Math, Physics, Chemistry, Psychology, Drama},

A = {Physics, History, Drama, Math},
B = {Chemistry, Psychology, French, Drama, Math},
C = {English, History, French}.
Find the following.
n(B) + n(C) equals:
a. 8
b. 7
c. 6
d. 5

Answer 1

To find n(B) + n(C), we determine the number of elements in set B and set C, and then add them. The answer is 8.

Step-by-step explanation:

To find n(B) + n(C), we need to determine the number of elements in set B and set C and then add them.

Set B = {Chemistry, Psychology, French, Drama, Math}

Set C = {English, History, French}

n(B) = number of elements in set B = 5

n(C) = number of elements in set C = 3

Therefore, n(B) + n(C) = 5 + 3 = 8

So, the answer is a. 8
