In class, 30% of students study Hindi, 45% study Maths, and 15% study both Hindi and Maths. If a student is randomly selected, what is the probability that he/she study Hindi or maths?

3/5

Students in Hindi = 30 %

Students in Maths= 45%

Students study both hindi and Maths = 15%

Students only in Hindi = 30% - 15% = 15%

Students only in Maths = 45% - 15% = 30%

Probability that students study both Hindi and English = \(\frac{15 + 15 + 30}{100}\)

= \(\frac{60}{100}\)

= \(\frac{3}{5}\)
