+61 
Could someone please confirm? I think the average is 4.2 and the mode is 1, if not could someone correct me?
+102 1. If you add all the values up together, you would get \(21\). Divide that by the number of days and you would get your mean (average): \(\frac{21}{5} = \) 4.2
2. Just count which number of cookies Grogg ate most in a day; the mode would be 1.
You are correct on all of them!
Hope that helped,

+874 (a) $\frac{1+11+3+5+1}{5}=\frac{21}{5}=\boxed{4.2}.$
(b) All other values except for $1$ appear exactly once. Thus the mode is $\boxed{1}.$
You are correct on both of them.
