Question

2. I can get to work by either riding my bicycle riding my motorcycle, or driving my car. I'm notoriously bad about maintaining my 3 transportation options. From previous experience, I know there's a 30% likelihood my bicycle will have a flat tire, a 37% likelihood my motorcycle battery will be dead (so it won't start), and a 81% chance that my car will run. I'm running late and I don't have time to fix any of these possible problems and still get to class on time. What is the likelihood I get to class on time? 3. In the previous problem, relative to just owning a car, how much does owning a motorcycle and a bicycle increase my odds of getting to class on time?

Answer 1

2 Probability of bicycle not working = 0.3 " I motorcycle , u = 0.37 11 carica (1-0.81 ) = 0.19 Now you cannot be on time it all of the 3 transportation optiony are not working. . Probability of all 3 modes not working = 0.3x0.37*0.19 0.0211 .. Likelihood of getting to class on time = 1-0.0211 - 0.9789 3) If you own only a car then odds of getting to class on time - 0.81 ~ 4.26 0:19 "If you own all three mocher then olds become - 0.9789 ~ 46.39 0.0211 So, the odds increase by almost 10.88 times.
