Question

In a class of all girls, 22 of the 28 students have brown hair. What is the

probability of randomly picking a girl without brown hair?

Answer 1

`(3)/(14)`

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
