a. Let 
be a random variable representing the weight of a ball bearing selected at random. We're told that 
, so
where 
. This probability is approximately
b. Let 
be a random variable representing the weight of the 
-th ball that is selected, and let 
be the mean of these 4 weights,
The sum of normally distributed random variables is a random variable that also follows a normal distribution,
so that
Then
c. Same as (b).
Answer:
27 slices of ham which is about 30% of the meat.
Step-by-step explanation:
In this problem we have given
no. of slices of meat=90
no of slices of turkey's meat=63
Percent of ham in platter=?
No of ham slices= Total slices -turkey slices
=90 - 63
= 27 slices
therefore no of ham slices=27
percent of ham slices=Ham slicesx100/total slices
=27x100/90%
=30%
Therefore percent of ham's in patter=30%
