probability he/she reads a newspaper is 30%
Explanation:
Given:
30% people read English newspaper
20% people read Hindi newspaper
20% of people read both newspapers.
solution:
30% people read English newspaper = 30/100 = 3/10
20% people read Hindi newspaper = 20/100 = 2/10
20% people read both newspapersr = 20/100 = 2/10
The probability that he/she reads a newspaper:
n(A U B) = n(A) + n(B) - n(A ∩ B)
= 3/10 + 2/10 - 2/10
= 3/10
hence, probability that he/she reads a newspaper is 3/10,
i.e, 30%
