A letter is chosen uniformly at random from {A, B, . . . , Z}. If that letter is one of the vowels (i.e. A, E, I, O or U) then a second letter is chosen uniformly at random from {A, B, . . . , Z}. Let L be the number of letters chosen and let V be the number of vowels chosen. (i) What is the expected value of L? (ii) What is the expected value of V?...

One of two small classrooms is chosen at random with equally likely probability, and then a student is chosen at random from the chosen classroom. Classroom #1 has 5 boys and 13 girls. Classroom #2 has 15 boys and 9 girls. What is the probability that Classroom #2 was chosen at random, given that a girl was chosen? Your answers should be rounded to 4 digits after the decimal.

The letters of “mississippi” are permuted randomly, with each distinguishable permutation equally likely. What is the probability that, in the resulting scrambled word, no four adjacent letters are all the same? That is, the four i characters cannot all be adjacent and the four s characters cannot all be adjacent. Give an exact answer as a simplified fraction.
