Option 3 : If both the statements I and II together are required to answer the question.

Statement I

The number of students of studies English = 40% of 100 = 40

Statement II

The number of students who studies Maths and Science = 100 – 40 = 60

The number of students who studies Maths and Science are in the ratio of 2 : 1

The number of students who studies Maths = 2/3 × 60 = 40

Required probability = 40/100 = 0.4

∴ Both the statements I and II together are required to answer the question.
