Suppose there are 30 people in a jury pool and the final jury will consist of 12 of these people. Suppose that among the 30, there are 17 whites and 13 non-whites. And suppose that the jury ends up being all white. What is the probability of this happening, if all possible 12-person juries has been equally likely?

Step-by-step explanation:

Total number of people, n = 30

number of white people = 17

number of non white people = 13

number of selected person which are white = 12

So, the number of ways to select the 12 white people out of 17 white people

=

the number of ways to select 12 white people out of total 30 people

So, the probability to select 12 white people out of 30 people is

16.9 times 2.85

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
