The new test designed for detecting TB is being analysed.
Denote the events as follows:
<em>D</em> = a person has the disease
<em>X</em> = the test is positive.
The information provided is:
Compute the probability that a person does not have the disease as follows:
The probability of a person not having the disease is 0.12.
Compute the probability that a randomly selected person is tested negative but does have the disease as follows:
Compute the probability that a randomly selected person is tested negative but does not have the disease as follows:
Compute the probability that a randomly selected person is tested negative as follows:
Thus, the probability of the test indicating that the person does not have the disease is 0.1452.
He multiplied rather than dividing.
Hope this helps!

Answer:
strawberry=7/8
Step-by-step explanation:
treat strawberry as x
add on proportions
1 1/8+ 3/4+ 1 3/4 + x = 4 1/2
(9+6+14)/8 + x = 9/2
29/8 +x = 9/2
x= 9/2 - 29/8
x= (36-29)/8
x=7/8
Answer:
B
Step-by-step explanation:
y = 2x - 4
y + 4 = 2x
x = y/2 + 4/2
x = y/2 + 2
—-
y = x/2 + 2
