Answer:
Number of Fares to airport is 25 and number of fares from airport is 25.
Step-by-step explanation:
Given:
Total Number of fares =50
Let number of fares to airport be x.
Let number of fares from airport be y.
hence the equation can be framed as;
Also Given
Total Money Collected = $375
Cost to airport = $10
Cost from Airport = $5
Total Money Collect is equal to Cost to airport multiplied by number of Fares to airport plus Cost from airport multiplied by number of Fare from airport.
Dividing by 5 on both side we get;
Now Subtracting equation 1 from 2 we get;
Substituting the value of x in equation 1 we get;
Hence Number of Fares to airport is 25 and number of fares from airport is 25.
Answer:
Probability that a student who passed the test did not complete the homework = 0.07
Step-by-step explanation:
Given:
Total number of students = 28
Number of students who passed the test = 18
Number of students who completed the assignment = 23
Number of students who passed the test and also completed the assignment = 16
To find: probability that a student who passed the test did not complete the homework
Solution:
Probability refers to chances of occurrence of some event.
Probability = number of favorable outcomes/total number of outcomes
Let A denotes the event that students passed the test and B denotes the event that students completed the assignment
P(A only) =
Here,
So,
Therefore,
probability that a student who passed the test did not complete the homework = 0.07
