Problema Solution
Abel's, Ben's, and Carl's names were each written on a slip of paper and placed in a box containing the names of nine other students. The teacher randomly drew three slips of paper without replacing them. What is the probability that the teacher drew the names Abel, Ben, and Carl, in that order?
Answer provided by our tutors
P(Abel first) = 1/12
P(Ben next) = 1/11
P(Carl third) = 1/10
P(drawing in order A, B, C) = (1/12) * (1/11) * (1/10)
P(drawing in order A, B, C) = 1/1320
