- the probability that a person has the virus given that they have tested positive is 0.0151.
- 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%).

Answer:
So, the original space of her garden was 20ftl + 4ftw. This makes her garden have a starting area of 80ft.
She then adds another 72ft (12ftl x 6ftw) which brings the total area to 152ft.
We have 152ft to work with here, if she wants to use 100 of those ft for vegetables, and the rest to plant fruits, we have to subtract 100 from 152 which gives us 52.
Answer:
The Fruits will take up 52ft of land.
Hope this helped!
check the picture below.
since we know all those interior points are midpoints, then those interior lines are midsegments, recall the midsegment is half the parallel base.
in this case, the green DF || AC, and since AC is 50, DF is half that, 50/2.
