Answer:
A is correct.
Explanation:
Given: (7,5) where (x, y)
Identify:
x = 7
y = 5
<u>Go 7 units through x-axis, then move up 5 units along the y-axis.</u>
The solution would be like this for this specific problem:
Given:
No
(Did Not Lie) Yes (Lied)
Positive Test Result 10 29
(Positive test indicated that the subject lied.) (false positive) (true positive)
Negative test result 66 18
(Polygraph test indicated that the subject did not lie.) (true negative) (false negative)
Find:
The
probability that all four test subjects had a true negative test result when
they are randomly selected without replacement.
Formula:
(66/123) x (65/122) x (64/121) x (63/120) = 0.0793864272
Therefore, when they are randomly selected without
replacement, the <span>probability that all four test subjects had a
true negative test result is 0.079</span>.
Answer:
The answer should be -2/5
