At a certain college, there were 400 science majors, 100 engineering majors, and 600 business majors. If one student was selected at random, the probbility that they are an engineering major is
Eng. majors/total students = ?
uhhhhh 1/1000
To find the probability that a randomly selected student is an engineering major, we need to know the total number of students at the college. Let's denote this number as "N."
The probability can be calculated as the ratio of the number of engineering majors to the total number of students:
Probability = Number of engineering majors / Total number of students
Given that there are 400 science majors, 100 engineering majors, and 600 business majors, the total number of students is:
Total number of students = Number of science majors + Number of engineering majors + Number of business majors
= 400 + 100 + 600
= 1100
Therefore, N = 1100.
Now we can calculate the probability:
Probability = Number of engineering majors / Total number of students
= 100 / 1100
= 0.0909 (rounded to four decimal places)
= 9.09% (rounded to two decimal places)
So the probability that a randomly selected student is an engineering major is approximately 0.0909 or 9.09%.
