In a survey of 200 people, 37% had a son, 31% had a daughter, and 23% had both a son and a daughter. What is the conditional pro
2 answers:
Answer: The conditional probability that a person who has a son also has a daughter is 62%.
Step-by-step explanation:
Since we have given that
Total number of people = 200
Let A be the event having son.
Let B be the event having daughter.
P(A) = 37%
P(B) = 31%
P(A∩B) = 23%
We would use "Conditional Probability" in which we have given that he has a son, and he now also has a daughter.
Hence, the conditional probability that a person who has a son also has a daughter is 62%.

To solve this we can take two different approaches:
1. We can substitute theta by 30° and evaluate our expression using a calculator:
2. We can use the unitary circle and the fact that
, so we can rewrite our expression as follows:
From our unitary circle we can check that
and 
.
Lets replace those values in our expression and simplify:
Either way we can conclude that the correct answer is: D)8.7
