Answer:
P(A' INTERSECTION B')= 1/6
Step-by-step explanation:
P(A)= 1/3
P(B)= 2/3
P(A INTERSECTION B)=1/6
P(A' INTERSECTION B')= P(A UNION B)' { DE-Morgan's Law)
P(A UNION B)= P(A) + P(B) - P(A INTERSECTION B)
P(A UNION B)= 1/3 +2/3 -1/6
P(A UNION B)= (2+4-1)/6 = 5/6
P(A UNION B)'= 1-5/6 = 1/6
P(A' INTERSECTION B') = 1/6
