Step-by-step explanation:
Given : Giving a test to a group of students, the grades and gender are summarized below
A B C Total
Male 8 10 7 25
Female 6 13 14 33
Total 14 23 21 58
Total students = 58
Total number of students got A = 14
P(students got A)
Total number of students got A and not female = 8
P( students got A and not female ) =
Now , By conditional probability ,
P(NOT a female | got a "A" ) =
∴ The probability that the student was NOT a female that got a "A" is .

Answer:
A. √16
Step-by-step explanation:
A perfect square is any number that can be expressed as a product of an integer and itself. i.e. 4 can be represented as 2 × 2. Therefore, 4 is a perfect square.
From the options given, the only radical expression that has two perfect square is √16.
√16 consists of two perfect squares, which are 4 and 4.
4 can be expressed as 2 × 2.
Thus: √16 = √(2 × 2)(2 × 2).
Therefore, √16 consists of two perfect squares.
