The Bottom Line Gift Boutique has been the target of many shoplifters in the past, but its newly installed camera security system has helped in the apprehension of 240 "sticky-fingered" customers in the last six months.
A breakdown of these 240 shoplifters revealed the following:
Males =140, 80 were first time offenders and 60 were repeat offenders
Females=100, 60 were first time offenders and 40 were repeat offenders.
What is the probability that the shoplifter is a first time offender, given that the shoplifter is a male?
