How many ways can you arrange 5 people for a photo?
I think this is a homework question so I'm giving only the method.
The answer is 5-factorial, expressed as 5!,
where the factorial of a number N is the product of:

The data from a normal distribution are symmetric about its mean, not about zero. There is, therefore nothing strange about all the values being negative.
The probability is 21/36 = 7/12
