A high school wants to assess the science elective courses that its students have chosen for their next year of education. Thirty-three freshmen, ten sophomores, eight juniors, and twenty-two seniors chose to take astronomy. Eighteen freshmen, twenty-four sophomores, thirty-three juniors, and twenty seniors are planning to take ecology. Twelve freshmen, thirty-eight sophomores, eighteen juniors, and twenty-five seniors want to take physics. Last, four freshmen, fourteen sophomores, fifteen juniors, and twenty-eight seniors chose to take chemistry.

Use this information to create a two-way frequency table and calculate the probability that a senior will take astronomy.
