Answer 1

I think will comma in b/w 21
Answer as per your question-
Data set = 1,1,2,2,2,3,21
Mean = sum total/total no. of frequency

$\frac{1+1+2+2+2+ 3 +21}{7} \\ \frac{32}{7} \\ 4.57$
4.57(approx)
Median = no. of frequency(n=7) is odd so
so n+1/2 th observation is your median
7+1/2th = 4th observation
so median is 2.
Mode = highest no. of occurence of a data
2 is occurring maximum so 2 is the mode.
