What else can I help you with?
In a classroom the students are 11 boys and 1 girl if one student is selected at random find the probability that the student is a girl?
There is only one girl out of 12 students so the probability that the girl is selected is 1/12.
What is the probability of asking a student at your school what grade he or she is in?
The probability is indeterminate. I might ask a student or I might not.
What is the probability that the student is a boy?
1/2.
In a second grade class containing 13 girls and 9 boys 2 students are selected at random to give out the math papers. What is the probability that the second student chosen is a boy given that the fir?
To find the probability that the second student chosen is a boy given that the first student chosen is a boy, we first note that there are 22 students total (13 girls and 9 boys). If the first student chosen is a boy, there will then be 8 boys and 13 girls remaining, making a total of 21 students left. Therefore, the probability that the second student is a boy is the number of remaining boys (8) divided by the total remaining students (21), which gives us a probability of ( \frac{8}{21} ).
What is the probability a randomly selected student earns and A or B on both exam scores 80 or higher?
There is insufficient information for us to answer this question. Please edit the question to include more context or relevant information.
What is the probability for a student in a dormitory to be selected if 10 percent of the students live in dormitories and a random sample of 100 is selected?
The probability is 10 percent.

In a classroom the students are 11 boys and 1 girls If one student is selected at random find the probability that the student is a girl?
1/12 =0.08333... ≈ 8.3%
What is the probability that two students will think of the same letter of the alphabet at the same time?
I think it depends on how many students are thinking of alphabet letters at the same time :) The first student will think of a letter from the English alphabet. Then, the second student will think of a letter. The probability that the second student will select what the first student selected is 1/26.
You randomly select 500 students and observe that 85 of them smoke Estimate the probability that a randomly selected student smokes?
85/500 = 17%
A class consists of 73 women and 18 men If a student is randomly selected what is the probability that the student is a man?
Since there are 73 Women, and 18 men, there are 91 people all together. The probability of the student being a man is 18 men out of the 91 total people. So, 18/91 or .1978.
There are 10 boys and 12 girls in a class if one student is selected at random from the class what is the probability it is a girl?
The probability is the number of girls divided by the number of students, so 12/22, or 6/11
What is the probability of asking a student at your school what grade he or she is in?
The probability is indeterminate. I might ask a student or I might not.

110
