Alittle league baseball team has been using an automatic pitching machine. if the machine is correctly set up (i. e. properly adjusted) it will pitch strikes 85% of the time. if it is incorrectly set up, it will pitch strikes only 35% of the time. past experience indicates that 75% of the setups of the machine are correctly done. after the machine has been set up at batting practice one day, it throws three strikes on the first three pitches. what is the revised probability that the setup has been done correctly?
