## In a class 30% of the students offered English, 20% offered Hindi and 10% offered both. If a student is selected at random, what is the probability that she/he offered English or Hindi?

### Solution(By Examveda Team)

Probability of English P(E) = 30 / 100 = 3 / 10,

Probability of Hindi P(H) = 20 / 100 = 2 / 10 and

Probability of Both Hindi and English P(E and H) = 10 / 100 = 1 / 10

P (E or H) = P (E) + P (H) - P (E and H)

= (3 / 10) + (2 / 10) - (1 / 10)

= 4 / 10 = 2 / 5
