standard deviation for a=3-2=1
in b)
number 4 ,7,9 and number 12 are showing 2 bullets while number 3 and 13 showing 1 bullet hence
standard deviation for a=2-1=1
in c)
number 4 ,7,9 and number 12 are showing 2 bullets while number 5 and 11 showing 1 bullet hence

It takes them 1 7/8 hrs to complete the job together.
How:
Fred = 3 hrs
Jason = 5 hrs
1/3x + 1/5x = 1/x
3x x 5x = 15 —> 3x/15 + 5x/15 = 15/15
3x + 5x = 8x —> 8x/15 = 1.875 = 1 7/8 hrs
