A chance experiment consists of drawing a raffle ticket from a box of tickets numbered 1, · · · , 40. Let Ω represent the sample space for this experiment. Since we select one ticket at random, Ω is an equally-likely sample space. Let E1,··· ,E8 where Ei ⊂ Ω be a partition of Ω defined as: E1 = {1,3,5,7,9}, E2 = {11,13,15,17,19}, E3 = {21,23,25,27,29}, E4 = {31,33,35,37,39}, E5 = {2,4,6,8}, E6 = {10,12,14,16,18}, E7 = {20,22,24,26,28}, E8 =...

4. Suppose an experiment consists of picking a student from the set of all students registered on the UCSD campus this quarter. It is not necessary to assume that all students are equally likely to be picked, but you may make this assumption if it makes you feel happier and more confident. (a) Consider the two events: Athe student has had four years of high school science (FYS, the student has had calculus in high school If the probability that...

4. (22pt) Danielle is performing an experiment where she draws a random card from standard deck, rolls a 6 sided dice, and draws a marble from a bag with 4 red, 5 green, 10 blue, and 12 white. Use this information to answer the following questions (be sure to write all probability answers as fractions AND decimals with 3 place values): a. How big is the sample space? b. Write out, exactly, what 3 possible outcomes might be. c. Let...

[2] [3] (5) (a) A soccer squad contains 3 goalkeepers, 7 defenders, 9 midfielders and 4 forwards. (i) In how many ways can a team of 1 goalkeeper, 4 defenders, 4 midfielders, and 2 attackers be chosen from this squad? (ii) Two of the defenders refuse to play together. In how many ways can a team be chosen that contains at most one of these two defenders? (b) Let p and q be real numbers. A random variable X has...

5. Consider a particle moving in the region x>0 under the influence of the potential U(x) = C (a/x + x/a), where C=1J, and a=2m. (a) Find the equilibrium positions and determine whether they are stable or unstable. (b) Find U at those equilibrium positions. (c) Sketch U(x) without using a computer (explain how you get the sketch) and discuss the motion of the particle in details in all the different regions if its total energy E1 = 2 J,...
