There is a 7% chance that a band’s lead singer’s voice isn’t working due to illness on any given Saturday. This band has played 19 Saturday 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 Saturday gig, which is 2 weeks from now? Assume she never is sick for more than 6 consecutive days, and the interval between bouts of illness is inherently unpredictable. Hint: You DO have enough information to provide a numerical answer for this question; in other words, “Not enough information” is incorrect.

Hope i can you!

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
