Explanation / Answer

4) P(VH) = 370/603

P(PH) = 215/603

P(VH AND PH) =0

P(VH OR PH) = P(VH) +P(PH) - P(VH AND PH)

= 370/603 + 215 / 603 - 0

= 0.97

5)

P(M) = 325/603

P(NTH) = 18/603

P(M AND NTH) = 9/603

P(M OR NTH) = P(M) + P(NTH) - P(M AND NTH)

= 325 / 603 + 18/603 - 9/603

= 0.553

6)

P(F) = 278/603

P(F AND VH) = 149/603

P(VH| F) = P( F AND VH) / P(F)

= (149/603) / (278/603)

= 0.535
