unConditionalprobGolf=numGolfRecords / total_Records

print("Unconditional probability of golf: ={}".format(unConditionalprobGolf))

#conditional probability of 'single' given 'medRisk'

numMedRiskSingle=2

numMedRisk=3

probMedRiskSingle=numMedRiskSingle/total_Records

probMedRisk=numMedRisk/total_Records

conditionalProb=(probMedRiskSingle/probMedRisk)

print("Conditional probability of single given medRisk: = {}".format(conditionalProb))

Output
