A medical test gives a correct result 90% of the time for infected individuals and 95% of the time for non-infected individuals. All members of the population are tested. The probability that a person is infected given they have a positive test result is 0.6. What proportion of the population is infected?

So

Hence,

Now

The probability that a person is infected is  

So the probability that a person is infected is =0.07692.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
