5. One shuffles at random the letters in RAZZMATAZZ. Find the probability that the new word also containts (5p) two non-adjacent pairs of 'ZZ':s, e.g., ZZAZZTARAM or MZZARAZZTA (but not AZZZZTARAM)? (5 p)
A point is chosen at random on a line segment of length 12. Find the probability that the ratio of the shorter to the longer segment is less than 3/20.
One of two urns is chosen at random with one just as likely to be chosen as the other. Then a ball is withdrawn from the chosen urn. Urn 1 contains 5 white and 2 red balls, and urn 2 has 4 white and 3 red balls. If a white ball is drawn, what is the probability that it came from urn 1?
In a uniformly random permutation of the vowels {a,e,i,o,u}, what is the probability that the first letter is i and the last letter is o?
An experiment consists of selecting a letter at random from the letters in the word CONNECTICUT. What is the probability that a vowel is selected? (Assume the vowels are {A,E,I,O,U}) Round to the second decimal

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.
