Answer: 0.0078
Step-by-step explanation:
We assume that cans of Coke are filled so that the actual amounts are normally distributed with a mean of 12.00 oz and a standard deviation of 0.12 oz.
As per given , we have
and 
Sample size : n= 5
Let
be the sample mean amount of coke in can.
Then, the probability that a sample of 5 cans will have a mean amount of at least 12.13 oz will be :_

[By using z-table]
Hence, the required probability = 0.0078
1.4 you subtract normally it as if you were doing whole numbers
Definition: The <u>probability</u> of an event happening is expressed as a fraction between 0 and 1.
Example: The <u>chance</u> that you roll a 4 on a die is 1
The answer to your math problem is m= 5/2
