There is a 4% chance that a band’s lead singer’s voice isn’t working (typically due to illness) on any given day. This band has played 19 gigs so far this year, and at each of these the lead singer’s voice has been fine. What is the probability that the lead singer’s voice will be fine at the band’s next gig, which is 2 weeks from now? Assume she never is sick for more than 7 consecutive days, and the interval between bouts of illness is inherently unpredictable.
