The probability that a randomly selected customer will have to wait between 32 minutes and 37 minutes is 59.81%
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Z score is given by:
z = (raw score - mean) / standard deviation
Given mean of 36 minutes and a standard deviation of 3 minutes.
For x = 32:
z = (32 - 36)/3 = -1.33
For x = 37:
z = (37 - 36)/3 = 0.33
P(-1.33 < z < 0.33) = P(z < 0.33) - P(z < -1.33) = 0.6179 - 0.0198 = 0.5981
The probability that a randomly selected customer will have to wait between 32 minutes and 37 minutes is 59.81%

Answer: The probability is 0.4
Step-by-step explanation:
Since the time taken to assemble a car in a certain plant is a random variable having a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = time taken to assemble cars
µ = mean time
σ = standard deviation
From the information given,
µ = 20 hours
σ = 2 hours
We want to find the probability that a car can be assembled at this plant in a period of time less than 19.5 hours. It is expressed as
P(x < 19.5) = 1 - P(x ≤ 19.5)
For x = 19.5
z = (19.5 - 20)/2 = - 0.25
Looking at the normal distribution table, the probability corresponding to the z score is 0.4
