Step-by-step explanation:
There are 14 fruit to start with and 2 bananas
2/14
then there are 13 fruit and 2 pears
2/13
So the probability of the two events in a row without replacement is:

Answer:
Adult ticket: $7 Student ticket: $11
Step-by-step explanation:
First, we set up our equations.
x (adult ticket) y(student ticket)
For the first day, 11x + 3y = 110
For the second day, 3x + 6y = 87
Then we solve.
(-2)11x + 3y =110
Equals
-22x - 6y = -220
Add them
-22x - 6y = -220
3x + 6y = 87
This equals
-19x = -133
x = 7
Plug in to find y
3(7) + 6y = 87
21 + 6y = 87
6y = 66
y= 11
