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.

Answer:
Low Frequency, Long Wavelength, and Low Energy Transfer
Explanation:
Radio waves are on the larger(and lower frequency) side of the electromagnetic spectrum. These longer wavelengths mean that radio waves have a lower frequency because it takes longer for larger waves to travel. Therefore, less radio waves can travel a certain distance in a minute than a wave of a shorter wavelenght(and therefore lower frequency). Radio waves are considered a low-energy transfer wave. This is because they can be used in most environments for communication, air-traffic control, and broadcasting with little to no harm to the organisms around them. Even though radio waves can be found all around us, because they don't carry much energy, we aren't harmed by the radio waves.
