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.
If two events are dependent on each other you have to multiply the probability of the first event times the probability of the second event.
first count all the marbles here there are 21
you are asked about picking two green marbles there are 7 out of the 21 total.
The first event would be 7/21
The second event would be 6/20 (since you didn't replace and you took out a green one)
now multiply your two fractions together:
and you get 1/10.
Answer:
a) 5/21
b) 4/21
c) 4/21
d) 8/21
Step-by-step explanation:
total number of coins: 21
a) number if dollars: 5
therefore fraction is 5/21
b) number of quarters: 4
therefore fraction is 4/21
c) number of dimes: 4
therefore fraction is 4/21
d) number of nickels: 8
therefore fraction is 8/21
