E is for "eight".


The number of fruit combinations would be the sum of all the different combinations--(have you had combinations? These are really easy to calculate with a calculator!!)--
One fruit DISABLED_event_only= C(7,1)=7
Two fruits = C(7,2) = (7*6)/(2*1) = 21
Three fruits = C(7,3) = (7*6*5)/(3*2*1) = 35
Four fruits = C(7,4) = 35
Five fruits = C(7,5) = 21
Six fruits = C(7,6) = 7
Seven fruits = C(7,7) = 1

Add these all up, 7+21+35+35+21+7+1 =127
