I attached the rest of your question in the image below.
We use the normal distribution density function f(z) to find the probability of a specific range of values.
Z= ((X-μ)/σ)
μ = 475σ = 8
a) X< 470 ml
P[X<470] = P[Z<(470-475)/8] = P[Z<(470-475)/8] = P[Z<-0.625] = 0.2659
b) 6 pack with a mean of less than 470ml
Z = ((X-μ)/(σ/√n))
Z = (470-475)/(8/√6)
P [Z<-1.53] = 0.063
c) 12 pack with a mean of less than 470ml
Z = ((X-μ)/(σ/√n))
Z = (470-475)/(8/√12)
P [Z<-2.165] = 0.0152

Answer: 5 * (1/6)</h3>
5 is the whole number, 1/6 is the unit fraction. A unit fraction is a fraction with 1 as the numerator.
We can think of 5 as 5/1
When we multiply 5/1 with 1/6, we get
(5/1)*(1/6) = (5*1)/(1*6) = 5/6
Use this rule to multiply fractions
(a/b)*(c/d) = (a*c)/(b*d)
You multiply the numerators together, and the denominators together.
