Answer:
Step-by-step explanation:
Total Students = 28
Brown Hair = 22
NOT Brown Hair = 28 - 22 = 6
The probability of an event is the number of that event divided by total number.
So, let denote probability of without brown hair be P(NOT BROWN). So, we can say:
P(NOT BROWN) = 6/28
Reducing, we get:
P(NOT BROWN) = 3/14
Given:
The given polynomial is:
To find the roots of the given polynomial.
To find the roots we have to take
So,
Formula
By quadratic formula, the root of the equation is,
and
Now,
Putting, we get,
and
and
Hence,
The values of the roots of the given polynomial are and
Hence, Option A and F are the correct answer.
