It has been a while since I've had to figure out summation notation.
Would you please look through my solutions, and tell me if they're correct?
Thank you so much! :)
1a.
6
Ʃ 1/6 = ?
i=1
1/6 + 1/6 + 1/6 + 1/6 + 1/6 +1/6 = 6/6 = 1
What makes me doubt my answer is that it seems like the i=1 was for nothing...
If the summation was for i/6, though, would this be correct?
(1/6) + (2/6) + (3/6) + (4/6) + (5/6) + (6/6) = 21/6 = 7/2
And if the summation were written like this:
6
Ʃ i/6 = ?
i=3
Would this be correct? (3/6) + (4/6) + (5/6) + (6/6) = 18/6 = 3
1b.
10
Ʃ 1/10 = ?
i=1
(1/10)*10 = 10/10 = 1
1c.
100
Ʃ 1/100 = (1/100)*100 = 100/100 = 1
i=1
