Answer:
1. 1120
2, 0.1071
Step-by-step explanation:
1.the number of distinguishable permutations of the given letters
AAABBBCD A is repeated 3, B is also repeated thrice
= 
=1120
2.If it begins with at least 2 A's , no. of permutations
=120
Therefore, the probability of random permutations of AA
=120/1120= 3/28= 0.1071

The average would be each number of cones sold per day added, and divided by the number of days (3). So this can be translated into the equation (67 + 59 + x)/3 = 60/1. Simplified, that is 67 + 59 + x = 180, then 126 + x = 180, then x = 54.
You can check by adding 67 + 59 + 54, which is 180, and divide by 3 days which is 60. So 54 cones were sold on Sunday.
