A pharmaceutical company has developed a test for a rare disease that is present in 0.5% of the population. The test is 98% accurate in determining a positive result, and the chance of a false positive is 7%. What is the probability that someone who tests positive actually has the disease? (Round your answer to two decimal places.)

The probability that someone who tests positive actually has the disease is  P(S|T)=0.43

Step-by-step explanation:

A pharmaceutical company has developed a test for a rare disease that is present in 0.5% of the population.

The test is 98% a positive result and the chance of a false positive is 7%

Let S be the event that the rare disease present

P(S)=0.05 and

Let T be the event that the test is positive

P(T)=0.98

Then we have to find the Conditional probability :

By using the formula for Conditional Probability is

=0.4294

=0.43

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

a 270° rotation about point p says on e d g e n u it y (had to space it out because it says it's a misspelling so i couldn't submit it
