Answer:
0.9739
Step-by-step explanation:
We have 1111+1414=2525 marbles, and
44 small white matbles and
1414-66=1348 big white marbles.
So we have 44+1348=1392 white marbles.
The probability to choose small marbles is P(s)=1111/2525=0,44
The probability to choose white marbles is:
P(w)=1348/2525=0,5513.
The probability to choose small and white is:
P(s and w)=44/2525=0,0174
The probability to choose small or white is:
P(s or w)= P(s)+P(w)-P(s and w)=0,44+0,5513-0.0174=0,9739
We will see that the cost of filling the tank is $38.88, and at the final of the trip she will have 4 gallons on the tank.
<h3>
How much costs to fill the tank?</h3>
a) The car holds 18 gallons, and it has 1/5 of the tank remaining.
Then in the tank there are:
(1/5)*18 = 3.6 gallons.
Then we need 18 gal - 3.6 gal = 14.4 gal
And each gallon costs $2.70, then to fill the tank, Miss Kito needs:
(14.4)*$2.70 = $38.88
b) Now we know that the car travels 26 miles per gallon, and she needs to travel a total distance of 364 miles.
Then she needs:

To travel that distance, and the car holds 18 gallons, so at the end of the trip, she will have 4 gallons of gasoline in her car.
