Events & Calendars Dan Velleman: "What to Expect in a Game of Memory"

Abstract: The game of memory is played with a deck of 2n cards. The cards are numbered from 1 to n, with each number appearing twice. The deck is shuffled, and then the cards are laid out facedown. A move consists of flipping first one card and then another. If the cards match, then both are removed from play. If not, they are flipped back over. Play ends when all pairs have been removed. In this talk, I will discuss the average number of moves required to complete a game of memory.

There will be pizza at this talk, but you must RSVP to awtorrey@amherst.edu by noon on Monday, Sept. 26.
