Step-by-step explanation:
Question,
in a group of 52 persons 16 speak English but not french and 33 speak English the number of persons who speak french but not English is
Answer,
We can solve this question using sets
Given,
- Total number of people = 52
- English speaking person = 33
- 16 speaks English but not french
Solution,
Formula
- Total people = n(A U B)
n(A)+n(B) - n (A ∩B)
Let's consider A is set of people talk English
Let's consider B is set of people talk french
n(A) = English speaking people =33
n(B) = french speaking people =?
n(A∩B) =who speak English and French=?
n(AUB) = TOTAL PEOPLE =52
n(A)-n(A∩B)=people who speak only English=16
n(A) - n(A ∩ B) = 16
33 - n(A ∩ B) = 16
n(A ∩ B) = 33 - 16
n(A ∩ B) = 17
People who speak English and French is 17
n(A U B) = n(A)+n(B) - n (A ∩B)
52 = 33 + n(B) - 17
n(B) + 16 = 52
n(B) =52-16
n(B) =36
Number of people who speak french
Question,
who speak french but not English
=n(B)-n(A ∩ B)
=36-17
=19
