Answer: The required probability is 0.414.
Step-by-step explanation:
Since we have given that
Probability of taxis in a certain city by Blue Cab P(B)= 15%
Probability of taxis by Green Cab P(G) = 85%
Let A be the event that eyewitness said that vehicle was blue.
P(A|B)=0.80
P(A|G)=0.80
P(A'|B)=0.20=P(A'|G)
Using the "Bayes theorem":
Probability that the taxi at fault was blue is given by
Hence, the required probability is 0.414.
