Zeno's Paradox

SUPPOSE THAT A MAN WANTS TO CROSS TO THE FAR WALL OF A ROOM THAT IS 20FT ACROSS. FIRST HE CROSSES HALF OF THE DISTANCE TO REACH THE 10 FT MARK. NEXT HE CROSSES HALFWAY ACROSS THE REMAINING 10 FT TO ARRIVE AT THE 5 FT MARK. DIVIDING THE DISTANCE IN HALF AGAIN HE CROSSES TO THE 2.5 FT MARK AND CONTINUES TO CROSS THE ROOM IN THIS WAY DIVIDING EACH DISTANCE IN HALF AND CROSSING TO THAT POINT BECAUSE EACH OF THE INCREASINGLY SMALLER DISTANCES CAN BE DIVIDED IN HALF HE MUST REACH AN INFINITE NUMBER OF MIDPOINTS IN A FINITE AMOUNT OF TIME AND WILL NEVER REACH THE WALL EXPLAIN THE ERROR IN ZENO'S PARADOX.

Problem solving using discrete structures

We worked on the attached problems today in class I am now trying to work through them again for understanding and I am not getting very far. My skills in discrete mathematics are not such that I can work through these on my own effectively. 3. Seven points are located in a plane. List the possible numbers of lines determined by these points. Your final answer is simply a list of whole numbers. You should indicate how each comes about. 4. Ten pieces of candy are distributed randomly to three children, Arlo, Burl, and Clovis. a. What is the probability that Arlo gets no candy? b. What is the probability that Arlo gets more candy than Burl and Clovis together? 5. In the grid be... click for more

Sequence defined recursively

4. A sequence is define recursively by A0 = A, and An+1 = An /1 + nAn. Determine A2001.

Problem of Probability

What is the probability that three letters from a set of five, picked one at a time will be in alphabetical order? I understand probability but unable to process at this time. Please help with the attached problem.

Problem of probability

Two individuals randomly picks marbles from different jars. What is the probability the one will pick more of one color then the other. I believe I can use the combination formula to solve, but am not sure how to apply it to this quesiton.
