a certain virus infects one in every 600 people. a test used to detect the virus in a person is positive 90% of the time if the
Alona [7]
  1. the probability that a person has the virus given that they have tested positive is  0.0151.
  2. the probability that a person does not have the virus given that they have tested negative is  0.9999

P(A) = 1/600 = 0.0017

P(B) = 0.9 * 0.0017 + 0.1 * (1 - 0.0017) = 0.1014

A) P (has the virus | tested positive) = P (tested positive | has the virus) ×  

                                                          P (has the virus)/ P (tested positive)

                                                         = 0.9 × 0.0017/0.1014  

                                                         = 0.0151

B) P (does not have the virus | tested negative) = P (tested negative | does not have the virus) × P (does not have the virus)/ P (tested negative)

= (1 - 0.1) *× (1 - 0.0017)/ (1 - 0.1014)  

= 0.9999

Probability is the department of mathematics regarding numerical descriptions of ways likely an occasion is to occur, or how possibly it's far that a proposition is genuine. The possibility of an occasion varies between zero and 1, wherein, roughly speaking, 0 suggests the impossibility of the occasion and 1 shows certainty. The better the possibility of an event, the more likely it is that the event will arise.  

A simple instance is the tossing of an honest (unbiased) coin. since the coin is truthful, the 2 results ("heads" and "tails") are both equally likely; the possibility of "heads" equals the chance of "tails"; and considering the fact that no different results are feasible, the possibility of both "heads" or "tails" is 1/2 (that could additionally be written as 0.5 or 50%).

max2010maxim [7]
<em><u>142.34 divide by 24 will give you the answer of 593.083 ----> </u></em>

<em><u>24 x 5 will equal 120 which is close to 142 then subtract 120 by 142 which will give you 22 then bring down the 3 and you will have 223 which 24 x 9 will give you 216 then subtract 223 -216 which gives you 74 then 24 x 3 = 72 then you add a decimal then a zero which is 20 then add another zero which is 200 then multiply 24 by 8 which is 192 and then subtract 200 by 192 and get 72 and then your answer will keep on going</u></em>.
