Answer:
10.55% probability
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the CDs are chosen is not important. So we use the combinations formula to solve this question.
1 Bach CD, from a set of 4.
1 Beethoven CD, from a set of 6.
1 Brahms CD, from a set of 3.
1 Handel CD, from a set of 2.
So, D=144
4 CDs from a set of 4+6+3+2 = 15.
So, T= 1365
p= D/T= 144/1365 = 0.1055
10.55% probability that she will choose one by each composer
Answer:
40 part-time male students were in the survey.
Step-by-step explanation:
Given:
Total number of students in the Phoenix high school = 100
Number of female student = 40
Number of male student who went to Phoenix Full time = 20 students
Total number of full time students = 50 students
To Find:
Number of part time male students in the survey = ?
Solution:
we know that the total number of students = 100
Now total number of male students = total number of students - total number of female student
Now total number of male students = 100 - 40 = 60 students
Now among these 60 students, 20 males went to Phoenix
Full time
So the remaining male students = 60-20 =40 students
Hence these 40 students are part-time male students
