-- October 1, 2010 Math 351 - Homework 7 1. Suppose we have three cards. The first is red on both sides, the second is blue on both sides. and the third is red Oil olle side and blue 011 the other. Label the sides of the first card as Rl and R 2 lahel the sides of the second card as BI and B2 and label the sides of the third card as Rand B. Do the following experiment: randomly pick one of the cards, make a note of the label on the nptnrned side and then make a note of the label on the reverse side.

### 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.
