Argelia is talking to her friend Adam about kayak fishing. She has been fishing many times on the Broad River, but she has never
recorded the number or types of fish she caught on her trips. She also has no idea how many fish are in the Broad River. Based on her experience, she tells Adam, that if they go fishing there next weekend, she would bet that he would have a 90% chance of catching a fish. What type of probability did Argelia use? Select one:
Subjective Probability Theoretical Probability Experimental Probability
We have been told that Argelia has been fishing many times on the Broad River, but she has never recorded the number or types of fish she caught on her trips. She also has no idea how many fish are in the Broad River.
Since we know that subjective probability is a probability based on an individual's personal judgement or past experiences about happening of some specific event. Subjective probability contains no formal calculations.
Upon looking at this problem we can see that this is indicating about subjective probability as this is based on Argelia's past experiences and she has never recorded the number or types of fish she caught on her trips.
Therefore, Argelia used subjective probability to tell Adam about having a 90% chance of catching a fish.
Using the quadratic formula works but if you know there are 2 answers (highest power of problem tells you how many solutions) then 10x^2 = 5x So either x = 0, giving 0=0. Or divide by 5x 2x = 1 x = 0.5
