A particular 12-hour digital clock displays the hour and minute of a day. Unfortunately,whenever it is supposed to display the number 1, it mistakenly displays the number 9. Forexample, when it is 1:16 PM. the clock incorrectly shows 9:96 PM. If we randomly watchthis clock for the whole day, what's the probability that the clock shows the correct time?
