What is the probability that a randomly selected crime happened in 2013 or was rape
P(total crime in 2013) = 9, 795 ,658/20014707
P(total rape) =164, 911/20014707
P(total rape in 2013)=79, 770/20014707
P(crime happened in 2013 or was rape) = P(crime in 2013) + P(rape) - P(crime in 2013 and rape) = (9795658/20014707) +(164911/20014707 - 79770/20014707=0.4937
