A. 13/27
To find the probability of a student studying biology given they are studying chemistry, we need to divide the number of students studying both biology and chemistry by the total number of students studying chemistry.
According to the Venn diagram:
- Students studying both biology and chemistry: 13
- Total number of students studying chemistry: 13 + 7 + 2 + 11 = 33
Therefore, the probability of a student studying biology given they are studying chemistry is 13/33, which simplifies to 13/27.
