The proportion of the drinks having the cost of more than 4 dollars in a coffee shop is two thirds.
<h3>What is a Uniform Density Curve?</h3>
Uniform Density Curve is given as the curve with the rectangle shape defining all the probabilities given for an outcome are identical.
The uniform density curve for the coffee shop have the been plotted as cost of drinks. The x-axis is the representation of the cost, and the plot is formulated one third from 3-6.
From the uniform density curve, the proportion of the drinks that are found to be costing in more than 4 dollars are two third, as one third lies for the cost up to 3 dollars.

Let Z be a random variable following the standard normal distribution with mean µ = 0 and standard deviation σ = 1.
The 67th percentile of the distribution is the value z that separates the bottom 67% of the distribution from the top 100% - 67% = 33%. In terms of probability, we have
Pr[Z ≤ z] = 0.67
Use the inverse CDF for the normal distribution (or lookup z scores in a table) to find
z = ɸ⁻¹(0.67) ≈ 0.4399
where ɸ(z) is the CDF for the normal distribution.
