Yeah, I need help. Easy question for most math experts, I'd guess, but I just hate probability. So here goes...
Joe and his two friends were shooting balloons at a carnival. They all made one shot and hit two balloons. Their respective probabilites for hitting the balloons were as follows: 0.2 for both of Joe's friends and 0.6 for Joe himself. Find the probability that Joe was the one who missed the shot.
Yup, I get that you're apparently supposed to use the Bayes' formula, but that knowledge doesn't really help me. So any outside help would be appreciated!
