Answer: a: No, Chloe was more likely to receive 2 call per day while it was not as likely she would receive any other amount.

b: There was a 7.14% chance to receive 0 calls in a day, 21.42% to receive 1, 42.84% chance of 2 calls, 17.85% of 3, 10.72% of 4, and 7.14% of 5 calls per day.

c: No, there is too large of an experiment group over the time frame to accurately form a theoretical probability.

d: Two phone calls, It was the most common occurrence over the month, and it had the highest percentage chance of all of the other occurrences.


Explanation:

b: To solve for this I took the #of days (28) and divided 100 by 28, this gave me 3.57. If you multiplied the # of calls by the answer given you got the percentage chance of calls/day. Equation Attached.


100/28=3.57\\  3.57 X 12(2 calls per day) = 42.84/100 or 42.84%
