Q:
# help please no rush

Accepted Solution

A:

To solve this, we take the number of subjects who weren't diabetic, and then divide them by the total number of subjects who took the test:

Probability = [tex] \frac{28}{3+28} [/tex]

= [tex] \frac{28}{31} [/tex]

= 0.903225..

= 0.90 (rounded)

-------------------------------------------------------------------------------------------------------------

Answer:

So the probability of randomly selecting a subject who was not diabetic would be 0.90 (the final option)

-------------------------------------------------------------------------------------------------------------

Note:

We only used the numbers under 'Negative Test', because the question wanted the probability 'given that the test result was negative'

Probability = [tex] \frac{28}{3+28} [/tex]

= [tex] \frac{28}{31} [/tex]

= 0.903225..

= 0.90 (rounded)
