In a certain algebra trigonometry class there are 6 male freshman's 8 female freshmen and 8 male sophomores, and 5 female sophomores. If a person is selected randomly from the group, find the probability that the selected person is a freshman or female
There are a total of 6 male freshmen + 8 female freshmen + 8 male sophomores + 5 female sophomores = 27 students in the class.
There are 8 female freshmen, so the probability of selecting a female freshman is 8/27.
There are 14 freshmen (6 male + 8 female), so the probability of selecting a freshman is 14/27.
Therefore, the probability of selecting a freshman or female student is 8/27 + 14/27 = <<8/27+14/27=22/27>>22/27. Answer: \boxed{\frac{22}{27}}.
