In an IB school 47 students study biology, 53 students study chemistry and 34 students do not study either of these two subjects. There are 109 students in this school. A student is selected at random. Given that this student does not study chemistry, find the probability that he/she studies biology. Give an exact answer as a fraction in fully simplified form or an approximate answer as a decimal rounded to three significant figures.
