There would be a 175/256 chance of being chosen at least once over the course of the year. Also, if you other students, as you no doubt will, simply look at Zach or my work, you really are not worthy of this class...
The probability of a specific employee not being tested would be about 32%, and therefore the probability of a specific employee being tested would be about 68% over the whole year.
I also gotta hand it to Ben for speaking his mind. Props.
The probability of not being chosen would be about 32%. To determine the chance of being chosen, I took this 32% and subtracted it from 100 to get a 68% of being tested.
likely hood of not being chosen over the course of the year would be (3/4)(3/4)(3/4)(3/4)= 31.64% so then subtracted from 100% to get the likely hood of being chosen would be 68.3%
The chance of being tested over the course of the year is about 68.3% and like Zach im going to have to give a virtual high five to Ben. To be sure he doesn't think I just looked at their answer, (3/4)^4= 32 (ish) so 100-32 is 68.
The probability of being chosen is 175/256 or .68359. I got this by finding the probability of not being chosen for the entire year [(3/4)^4] and subtracting it from 1.
There would be a 68% chance of being tested over the course of the year. To get this i subtracted the chance of not being chosen from one then put that anser to the fourth. so it looks something like this, 1-(3/4)^4=.684 or 68%.
This is just like what we have been doing in class, which is finding what we are looking for by finding what we are not looking for and then subtracting that from 100%. Therefore, we would be looking for what is not wanted which is the probability of NOT being picked for the trial which is (3/4) but since it is over the course of 4 trials it would (3/4)(3/4)(3/4)(3/4) = 31.64% By subtracting 31.64 from 100 you would get 68.35. Although this may seem logical the question itself is somewhat wordy and can be interpreted differently.
Assuming that the question is asking the probability of being chosen at least once over an entire year, the answer would be about 68.359%. the total possibilites of not getting picked + getting picked at least once = 1. therefore the probability of getting picked at least once is equivalent to 1-not (1- (3/4)^4) = .68359 or 68.359%. Yet the theoretical probability of getting chosen will always remain the same at 25% regardless of the durration of time.
There's a 68.36% chance of being chosen over the course of a year. In order to find this value I found the probability of never being tested by doing this: (3/4)^4 = .3164. Then once I found this number I subtracted it from 1 to find the probability of being tested: 1 – 0.3164 = .6836
I found a 68.4% chance of being chosen over the course of a year. (Probability of never being tested = (3/4)(3/4)(3/4)(3/4) = .316. 1- .316 = .684, .684 x 100 = 68.4% chance of not being chosen).
There us a probability of being chosen of 68.4% or 175/256. I found this answer through subtracting the probability of not being chosen for the entire year - (3/4)^4) - from 1.
You would have a 175/256 chance of being chosen over the course of the year; a 68.36% chance.
ReplyDeleteThere would be a 175/256 chance of being chosen at least once over the course of the year. Also, if you other students, as you no doubt will, simply look at Zach or my work, you really are not worthy of this class...
ReplyDeleteThe likelihood of being chosen over the course of one year is 68.7%, or 1-P(Not being chosen)^4.
ReplyDeleteThere would be a 68% chance that you would be chosen over a year.
ReplyDeleteThe probability of not being chosen is about 32%:
ReplyDeleteNNNN: (3/4)(3/4)(3/4)(3/4) = 81/256 or 31.64%
When 32% is subtracted from 100% the probability of being chosen is about 64%.
Probability of never being tested = (3/4)^4 = .3164
ReplyDeleteProbability of being tested = 1-probability of never being tested = .6836

the probability of being tested is 68.359% over the course of a year.

ReplyDeleteI also gotta hand it to Ben for speaking his mind. Props.
you have a 68% chance of being tested throughout the year
ReplyDeleteThe probability of not being chosen would be about 32%. To determine the chance of being chosen, I took this 32% and subtracted it from 100 to get a 68% of being tested.
ReplyDeletethe probability of a specific employee not being tested: (3/4)^4 = .32
ReplyDeleteprobability of a specific employee being tested: 1-.32 = .68
which means you have a 68% chance of being tested throughout the year
The probability of being chosen is 1 - probability of not being chosen or 1-(.75^4) which is 68%.
ReplyDeletelikely hood of not being chosen over the course of the year would be (3/4)(3/4)(3/4)(3/4)= 31.64% so then subtracted from 100% to get the likely hood of being chosen would be 68.3%

ReplyDeleteThere would be a 68% chance over the course of the year.
ReplyDeleteThe probability of being chosen is 1-the probability of not being chosen, so 1-(3/4)^4=.684 or 68.4%

ReplyDelete1-(3/4)^4=.684, meaning that there is a 68.4% chance of being chosen over the course of the year.
ReplyDeleteThe probability of being chosen is 68.4%. I got this by subtracting the probability of not being chosen (which is (3/4)^4) from 1.
ReplyDeleteProbability of not being tested= (3/4)(3/4)(3/4)(3/4)=.32 or 32%
ReplyDeleteProbability of being tested = 1-.32=.68 or 68%
you would have about a 68% chance of being tested.
The probability of being chosen would be about 68% because the probability of not being chosen would be (3/4)(3/4)(3/4)(3/4) or about 32%.

ReplyDeleteThe probability of not being tested is 3/4^4 or .3164. That's 31.64% of not being chosen. The difference is 68.36% chance of being chosen.
ReplyDeleteThe probability of not being chosen over the course of a year is .316 therefore the probability of being chosen is 68.4%
ReplyDeleteI found a 68.4% chance of being chosen over the course of a year. (Probability of never being tested = (3/4)(3/4)(3/4)(3/4) = .316. 1- .316 = .684, .684 x 100 = 68.4% chance of not being chosen).
