### 10 points for simple Probability normal distribution question!?

Bottles at a boteling company are supposed to contain 375ml of soda. But the contents vary according to a normal distribution, with mean=373ml and standard deviation=3ml.

i)What is the probability that an indevidual bottle contains less than 375ml of soda?

ii) whats the probability that the mean contents of the bottles in a six pack is less than 375ml?

iii)What is the probability that the total volume of two bottles selected at random will be greater than 750ml?

okey, so i got the first answer, using statistical tables (normal distribution), im just not sure what approach i should take for more than one bottle etc.

Just got no idea on how to answer ii) and iii) any help would be greatly appriciated ;)
