The probability all of the students in this class will be present and on time is 3/10. The probability all of the students are p resent is 2/5. What is the probability that everyone is on time given that everyone is present? Give your answer as a simplified fraction.
1 answer:
Answer:
3/4
Step-by-step explanation:
A: students present
P(all students present and on time) = P(A and B) = 3/10
P(A and B) = P(A).P(B|A) where P(B|A) is the probability of everyone being on time given that everyone is present15/20 which can be reduced to 3/4 by dividing numerator and denominator by 5

Answer:
54 students
Step-by-step explanation:
First, change the percent to a decimal.
12% = 0.12
Now, multiply the decimal by the total amount of students to find the amount of students that stay after school.
450 × 0.12 = 54
