Answer:
Step-by-step explanation:
Thinking process:
Let the total set be the combination of all the sets as shown

Therefore the probability =
=
=
380 cookies divided by 5 hours is equal to 76 cookies per hour.
To get the average, you must add all together and divide by the amount of numbers there are
(-4 - 6 - 3 - 1 + 0 + 2 - 1 - 3)/ 8
(-16)/8 = -2
-2 is your average
hope this helps
