Answer:

The responsess to the given question can be defined as follows:

Step-by-step explanation:

$P(medication\ used) = 0.007 \\\\P( drug \not\ used ) = 1 - 0.007 = 0.993\\\\P(test\ positive | medication \ used) = 0.96 \\\\ P(test \ negative | medication \ used) = 1 - 0.96 = 0.04\\\\$

$P(Point | Non-used\ medication )=0.93\\\\ P(Point |No\ medication ) = 1 - 0.93 = 0.07$

As per the given info we draw the tree diagram which is defined in the attachment file.

$P ( test \ is\ positive ) = P( medication \ used ) \times P( Test \ positive | medication \ used ) + P( medication not \ used ) \times P( Test\ positive | medication \ not \ used )$

$= ( 0.007 \times 0.96 ) + ( 0.993\times 0.07 )\\\\= 0.0762$

$P( medication \ used | test\ positive )= \frac{\textup{P( medication used ) *P( Test positive given medication used )}}{\textup{P( medication used )}}$

$= \frac{( 0.007\times 0.96 )}{0.0762}\\\\= 0.0882$

$\sf{Hey!}$

$\boxed{\underline{Question:}}$

$(\frac{1}{5})^4 = \frac{1}{632}$

If you want the decimal.

$^A^n^s^w^e^r^~:$

$0.0016.$

$\huge\bold{\textbf{\textsf{{\color{EXPLANATION :}{}}}}}$

Apply exponent rule: $(\frac{a}{b})^c =\frac{a^c}{b^c}$

= $\frac{1^4}{5^4}$

$1^4=1$

$=\frac{1}{5^4}$

$5^4=625$

= $\frac{1}{625}$

Hope It Helps. . .
