What is the probability that a randomly chosen u. S. President is left-handed and a democrat?.
sashaice [31]

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)}

In which

  • P(B|A) is the probability of event B happening, given that A happened.
  • P(A \cap B) 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)}

0.13 = \frac{P(A \cap B)}{0.4}

P(A \cap B) = 0.13(0.4)

P(A \cap B) = 0.052

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

What’s (2a) with an exponent of 6/5 in radical form?
VashaNatasha [74]
<h3>Answer: Choice A</h3>

Reason:

Use the rule that a^{b/c} = \sqrt[c]{a^b} = \left(\sqrt[c]{a}\right)^b

This means, (2a)^{6/5} = \sqrt[5]{(2a)^6} = \boldsymbol{\left(\sqrt[5]{2a} \ \right)^6}

As another example, m^{2/3} = \sqrt[3]{m^2} = \left(\sqrt[3]{m} \ \right)^2
