In a market, the average expiration time for all milk (package with carton?) is 9.6 days. For all x, the amount of the milk with an expiration greater than 9.6+x is equal to the milk with an expiration less than 9.6-x. If the expiration for 68% of the milk is greater than (or within?) 2.1 days, what percent of milk have expiration greater than 11.7 days?
A 16%
B 32%
C68%
D 84%
D 96%
b – 32%
I think i will go with:
