Homework Problem Set No. 4 – Physics 17 Due in class, Wednesday, October 29 1. Consider a classroom of N seats and n students attend class. How many different seating arrangements are there? (Assume n < N ). Consider the same situation, but iden- tical clones instead of individual students are attending class. How many different seating arrangements are there? 2. Consider an unusual coin which has a 75% chance of heads and 25% chance of tails. After 10 6 tosses, what is the expected number of heads? For 99% of all experiments, what are the minimum and maximum number of heads that will be achieved? 3. Assume you take a trip to Los Vegas and make 100 \$1.00 bets.

Unformatted text preview: a 49% of winning a bet and a 51% chance of losing a bet. What are the odds that you will be a net winner? What are the odds that you will leave Los Vegas with at least \$150? 4. Consider a particle of mass m in a 1-D box of length a . For large values of E , compute the number of states the particle can have with energy ≤ E . Now perform the same calculation for a 2-D box of sides of length a . 5. In the general population, 1 person in 10 is left-handed. In a class of 39 students, what are the odds that there are (1) 0 left-handed people, (2) 2 left-handed people, and (3) 39 left-handed people? 1...
