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:
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:
0.052 = 5.2% probability that a randomly chosen U. S. President is left-handed and a democrat.

Based on <u>the </u><u>norm</u><u> of </u><u>reciprocity</u>, you will feel obligated to do a favor for a coworker when he or she performs a large favor for you.
<h3>What is the norm of reciprocity?</h3>
The norm of reciprocity can be defined as a social convention requires that a person repay in kind a favor or assistance that was done to them, especially to the performer of such act.
Based on <u>the </u><u>norm</u><u> of </u><u>reciprocity</u>, we can infer and logically deduce that you will feel obligated to do a favor for a coworker when he or she performs a large favor for you.
