Bottles of wine are stacked in racks of 12. The weights of these bottles are normally distributed with
mean 1.3 kg and standard deviation 0.06 kg. The weights of the empty racks are normally distributed
with mean 2 kg and standard deviation 0.3 kg.
(i) Find the probability that the total weight of a full rack of 12 bottles of wine is between 17 kg and

The total weight is the sum of two normally distributed values
The first step is to find the mean and std dev of total weight.
The mean will be the mean of the two distributions that you are adding
the variance (square of std) will be the sum of the two variances
Can you find the mean and variance of the total weight?
i was able to find the mean.. but the variance was not correct
to find the variance, for find the variance of the wine and of the rack
what do you get for them ?
