Starting from the point (10 , 6) how many paths are there that reach the point (100 , 40) that also go through a point ( n, 0) for some 10 < n < 100. 3. In an Urn there are 3 black balls numbered 1 to 3, 3 white balls , numbered 4 to 6 and 3 red balls, numbered 7 to 9. How many different 6 digit numbers can be formed in this way by using the digits on all possible selections of 2 black balls, 2 white balls and 2 red balls. 4. In a 10 digit number each digit is one of the digits 1 to 9. How many such numbers are there if the digit 3 occurs exactly 4 times? 5.

    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.
