Answer:

.3375

Explanation:

Total people who were given drug: 800

Total people who showed improvement: 270

Probability:

[tex]\boxed{ \sf \dfrac{favorable \ outcomes }{total \ possible \ outcomes}}[/tex]

insert values

[tex]\rightarrow \sf \dfrac{270}{800}[/tex]

simplify

[tex]\rightarrow \sf \dfrac{27}{80}[/tex]

in decimals

[tex]\rightarrow \sf 0.3375[/tex]

Answer:

d)  .3375

Step-by-step explanation:

let E be the event : “the patient shows improvement”

    D be the event : “the patient was given the drug”

here we are in a conditional probability situation:

Let E/D be the event “a patient shows improvement ,if it is known that the patient was given the drug”

[tex]p\left( E|D\right) =\frac{p\left( E\cap D\right) }{p\left( D\right) }[/tex]

            [tex]=\frac{270}{800}[/tex]

            [tex]=0.3375[/tex]
