Question 6. Suppose you model the entropy of a system by flipping, simultaneously, 100 identical coins each with one side heads and the other tails. 100 Coins 1E+29 8E+28 6E+28 4E+28 2E+28 0 The numbers on the right hand side are the multiplicities and the numbers on the bottom are the number of heads+1. The number of ways, in a single toss, to get a given number of heads is the multiplicity. Which number of heads, 5, 35, 53, 67...

Problem 6 A box contains 4 coins: • coin 1 has both sides heads. • coin 2 has both sides tails. • coin 3 has both sides tails. • coin 4 is a regular coin (1 side head, other side tails). (a)(3 points) If we randomly choose one coin from the box and flip, what is the probability we get heads? (b)(3 points) If we randomly choose one coin, flip, and it comes up heads, what is the probability it...

We are given three coins. One has heads on both faces, the second has tails on both faces, and the third coin has a head on one face and a tail on the other face. We choose one coin at random, toss it, and observe that the result is heads. What is the probability that the opposite face is tails?

A box contains five coins. For each coin there is a different probability that a head will be obtained when the coin is tossed. (Some of the coins are not fair coins!) Let pi denote the probability of a head when the i th coin is tossed (i = 1, . . . , 5), and suppose that p1 = 0, p2 =1/4, p3 =1/2, p4 =3/4, p5 =1. The experiment we are interested in consists in selecting at random...

A box contains four coins. Three of the coins are fair, but one of them is biased, with P(11) = ? (where 11 is the event of flipping heads). You take a coin from the box and flip it. It comes up heads. What is the probability that you have flipped the biased coin?

Make a table. Lay the 100 pennies with heads facing up in the bottom of the box. In the first table row (Trial #1), record that 0 pennies were removed (none of them are tails up). Then, record that 100 heads up pennies are left in the box. With 100 pennies showing heads up in the box, close the box and shake it for 3 seconds, then place it on a flat surface. Open the box and count all of...
