Answer:

The answer is "0.95 and 0.5271".

Step-by-step explanation:

$p (d) = 0.905 \\\\p( false\ negative) = 0.05\\\\p(false \ positive ) = 0.10 \\\\$

In point a)

p ( positive diabetes ) $= 1 - 0.05 = 0.95$

In point b)

$p(\frac{d}{+ve}) = \frac{0.105 \times 0.95}{0.105 \times 0.95 +0.895 \times 0.10 }$

$=\frac{0.09975}{0.09975+0.0895}\\\\=\frac{0.09975}{0.18925}\\\\= 0.5271$
