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.

Suppose that IQ scores have a bell-shaped distribution with a mean of 101 and a standard deviation of 12. Using the empirical ru

7nadin3 [17]

95.44% IQ scores are between 77 and 125

We're given,

Mean (a)=101

standard deviation (b)=12

To find : $P[77 < x < 125]$

Using Empirical Rule:

∴ $P[77 < x < 125]$ $=$ $P[\frac{77-101}{12} < \frac{x-a}{b} < \frac{125-101}{12}]\\$

$=P[-2 < z < 2]\\$

$=P[Z < 2]-P[Z < -2]\\$

$=0.9772-0.0228\\$

$=0.9544$ =95.44% (approx)

It'll go straight. You need to cut the throttle to idle, then make a hard right. The PWC will have no control at that point.
