Question 1174460: . In a certain city, sports bikes are being targeted by thieves. Assume that the probability of a sports bike being stolen is 0.09 while the probability is only 0.5 for a regular bike. Taking, as an approximation for all bikes in that area, the nationwide proportion 0.19 of sports bikes, find the probability that a stolen bike is a sports bike.

b. 0.02
c. 0.01
d. 0.03

Sports bikes ---> 0.19 * 0.09 = 0.0171
Regular bikes ---> 0.81 * 0.5 = 0.4050

0.0171%2F%280.0171%2B0.4050%29 = 0.0171%2F0.4221 = 0.04
