2 Sammy counts the number of people in one section of the school auditorium.
He counts 18 female students, 16 male students, and 6 teachers. There are
720 people in the auditorium. Consider the probability of selecting one person
at random from the auditorium.
Which of these statements are true?
Choose all that apply.
A
The probability of selecting a teacher is 6%.
B
The probability of selecting a student is 85%.
C
The probability of selecting a male student is 32%.
D
The probability of selecting a female student is 45%.

Step-by-step explanation:

In auditorium the following data gives the number of people in one cross section.

The number of female students = 18

The number of male students = 16

The number of teachers = 6

The total number of people in one cross section = 40.

(i) The probability of selecting a teacher = = 15%

Option A is wrong

(ii) The probability of selecting a student = = 85%

Option B is correct

(iii) The probablity of selecting a male student =   = 40%

Option C is wrong

(iv) The probablity of selecting a male student = = 45%

Option D is correct

Teachers - 15% | Male students - 40% | Female students - 45%

Step-by-step explanation:

18+16+6=40

40x18=720

18/40=45

16/40=40

6/40=15

boom.
