Using conditional probability, it is found that there is a 0.052 = 5.2% probability that a randomly chosen U. S. President is left-handed and a democrat.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a previous event. The formula is:
![P(B|A) = \frac{P(A \cap B)}{P(A)}](https://tex.z-dn.net/?f=P%28B%7CA%29%20%3D%20%5Cfrac%7BP%28A%20%5Ccap%20B%29%7D%7BP%28A%29%7D)
In which
- P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, the events are:
- Event A: President is left-handed.
- Event B: President is a democrat.
Researching the problem on the internet, it is found that:
- 40% of the presidents were left-handed, hence P(A) = 0.4.
- If a president is left-handed, there is a 13% chance that the president is a Democrat, hence P(B|A) = 0.13.
Then:
![P(B|A) = \frac{P(A \cap B)}{P(A)}](https://tex.z-dn.net/?f=P%28B%7CA%29%20%3D%20%5Cfrac%7BP%28A%20%5Ccap%20B%29%7D%7BP%28A%29%7D)
![0.13 = \frac{P(A \cap B)}{0.4}](https://tex.z-dn.net/?f=0.13%20%3D%20%5Cfrac%7BP%28A%20%5Ccap%20B%29%7D%7B0.4%7D)
![P(A \cap B) = 0.13(0.4)](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D%200.13%280.4%29)
![P(A \cap B) = 0.052](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D%200.052)
0.052 = 5.2% probability that a randomly chosen U. S. President is left-handed and a democrat.

Explanation:
North/South America:
New World monkeys inhabit the New World, which includes North and South America.
Africa and Asia:
Prosimians, the earliest of the primates, inhabit regions of Africa and Asia.
Old World monkeys still live in Africa and Asia. Fossil species also lived in Europe.
Apes are Old World primates. They are found today in Africa and Asia.
<h3>What is the group of Primates?</h3>
The primates are;
- New World monkeys
- Prosimians
- Old World monkeys
- Apes
The groups are;
North/South America
Africa and Asia
New World monkeys inhabit the New World, which includes North and South America.
Prosimians, the earliest of the primates, inhabit regions of Africa and Asia. This also applies to Apes and Old monkeys.
Thus;
North/South America:
New World monkeys inhabit the New World, which includes North and South America.
Africa and Asia:
Prosimians, the earliest of the primates, inhabit regions of Africa and Asia.
Old World monkeys still live in Africa and Asia. Fossil species also lived in Europe.
