the table shows the enrollment in a university class so far, broken down by student type.\n| adult education | 7 |\n| graduate | 2 |\n| undergraduate | 9 |\nconsidering this data, how many of the next 12 students to enroll should you expect to be undergraduate students?\n\n undergraduate students
Answer
Explanation:
Step1: Calculate total students so far
$7 + 2+9=18$
Step2: Calculate probability of undergraduate
The number of undergraduate students is 9 out of 18, so the probability $P=\frac{9}{18}=\frac{1}{2}$
Step3: Predict number of undergraduates in next 12
Multiply the probability by 12. $12\times\frac{1}{2} = 6$
Answer:
6
