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
a=6, b=2
Step-by-step explanation:
Use simplification into substitution
We can now plug this value of <em>a</em> into the second equation.
Get rid of fractions in the numerators and/or denominators
Then we can match the denominators
Combine
Divide both sides by three
Get rid of fractions
Single out <em>b</em>
Now we can plug it into the equation
Now we can check it;
