Answer:
The answer is C (5) on Edge.
Step-by-step explanation:
Answer: 5
For how many teachers are both p ∧ r true and q false?
(p ∧ r) ∧ (q')
q' = q complement (not in q)
p intersection r = (p ∧ r) = 9
both p ∧ r true and q false = (8+6) - 9
both p ∧ r true and q false = 14 - 9 = 5
OR
p + r - p ∧ r
8 + 6 - 9 = 14 - 9 = 5
B is the the answer but I'm not sure
(a) 0.2707
(b) 0.8576
9/10
