Each morning, before they go off to work in the mines, the seven dwarves line up and Snow White kisses each dwarf on the top of his head. In order to avoid any hint of favoritism, she kisses them in random order each morning. (a) What is the probability that the dwarf named Bashful gets kissed first on Mon- day? (b) What is the probability that Bashful gets kissed first both Monday and Tuesday? (c) What is the probability that Bashful does not get kissed first, either Monday or Tuesday? (d) What is the probability that Bashful gets kissed first at least once during the week (Monday Friday)? 2. Alice and Bob roll a standard die obtaining a number at random from 1 to 6.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
