Explanation / Answer
A)P (A2 | A1) = P(A2 and A1) / P(A1)
= 0.05/0.22 = 0.2273
B) P(A2 and A3 | A1) = P(A2 and A3 and A1) /P(A1)
= 0.01/0.22 = 0.0455
C) P(A2 U A3) | A1) = P((A2 U A3) and A1) / P(A1)
= (P(A2 and A1) + P(A3 and A1) - P(A2 and A1 and A3 and A1)) / P(A1)
= (0.05 + 0.09 - 0.01) / 0.22 = 0.5909
D) P((A1 and A2 and A 3 ) and (A1 U A2 U A 3)) / P(A1 U A 2 U A 3)
= P(A1 and A2 and A 3) / P(A1 U A 2 U A 3)
= 0.01/0.52 = 0.0192
