Given that P = {x : 1 \(\leq x \leq 6\)}, and Q = {x : 2 \(\leq x \leq 10\)} where x is an integer. Find n(P \(\cap\) Q)
A
5
B
6
C
8
D
10
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
P = {1, 2, 3, 4, 5, 6}; Q = {3, 4, 5, 6, 7, 8, 9}
P \(\cap\) Q) = {2, 3, 4, 5, 6}
n(P \(\cap\) Q) = 5
