How many months of the year have 31 days? Jan, Mar, May, Jul, Aug, Oct, Dec. That's 7 months out of 12. Thus, if you were to pick a month from these 12, the chances that you'd pick one that had 31 days would be 7/12, or approx. 0.58.

In this case, n = 8; A1 = - 11, r = -4

S8 = -11 (1 - (-4)^8) / (1 -(-4)) = 144,177
