The results of a medical test show that of 39 people selected at random who were given the test, 33 tested negative and 6 tested positive. Determine the odds against a person selected at random from these 39 people testing negative on the test.

Given Information:

Total number of people = 39

Number of people who tested negative = 33

Number of people who tested positive = 6

Required Information:

Probability of finding a person who tested negative = ?

P( x = 1 ) = 0.000315 = 0.0315%

Step-by-step explanation:

Let the probability of success is denoted by those who test negative,

p = 33/39

p = 0.85

Then the probability of failure is denoted by those who test positive,

q = 1 - p = 1 - 0.15 = 0.85

We want to find out the probability of finding a random person who test negative.

P( x = 1 ) = (p³⁹⁻¹)(1 - p)¹

P( x = 1 ) = (0.85³⁹⁻¹)(1 - 0.15)¹

P( x = 1 ) = 0.0021*0.15

P( x = 1 ) = 0.000315

Therefore, the Probability of finding a person who tested negative is 0.0315%

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

step-by-step explanation:

because it just is
