Question #1
A study records literacy (A) and employment (B) in a population of 1000. Given (A)=600, (B)=700, (AB)=450. The coefficient of association suggests:
A. Perfect positive association
B. No association (independence)
C. Negative association
D. Positive association

Correct Answer: Option D


Explanation:
Expected (AB) under independence = (600×700)/1000 = 420. Observed (AB)=450 > 420, indicating positive association. Yule's Q = [(450×150) - (150×250)] / [(450×150) + (150×250)] = (67500-37500)/(67500+37500)=30000/105000≈0.286, confirming positive but not perfect association.

Question #2
A card is drawn from a well-shuffled deck of 52 cards. The probability that it is a jack or a spade is:
A. 4/13
B. 1/4
C. 16/52
D. 17/52

Correct Answer: Option C


Explanation:
P(jack)=4/52, spade=13/52, jack of spades=1/52. P=4/52+13/52-1/52=16/52.

Question #3
Given P(A)=0.7, P(B)=0.5, and P(A∩B)=0.45. Which statement is correct?
A. A and B are independent.
B. A and B are dependent, and P(A|B) = 0.9.
C. P(A∪B) = 0.8.
D. A and B are mutually exclusive.

Correct Answer: Option B


Explanation:
P(A|B)=0.45/0.5=0.9 ≠ P(A)=0.7, so dependent. P(A∪B)=0.7+0.5-0.45=0.75 ≠ 0.8.
