Expert Solution
Given Data:

Probability that policy holder is married = P(M) = 0.56

Probability that policy holder have atleast one child = P(C) = 0.67

Probability that policy holder is married and have atleast one child = P(M  C) =  0.41 

 

Required Probability:

Probability that policy holder is married OR has a child:

P(M  OR  C ) = P(M) + P(C) - P(M and C)

P(M  OR  C ) = 0.56 + 0.67 - 0.41

P(M  OR  C ) = 0.82
