Suppose the time it takes a barber to complete a haircuts is uniformly distributed between 8 and 22 minutes, inclusive. Let X =
salantis [7]

Answer:

P(X>14)= 1-P(X

And replacing we got:

P(X>14)= 1- \frac{14-8}{22-8}= 0.5714

The probability that a randomly selected barber needs at least 14 minutes to complete the haircut is 0.5714

Step-by-step explanation:

We define the random variable of interest as x " time it takes a barber to complete a haircuts" and we know that the distribution for X is given by:

X \sim Unif (a= 8, b=22)

And for this case we want to find the following probability:

P(X>14)

We can find this probability using the complement rule and the cumulative distribution function given by:

P(X

Using this formula we got:

P(X>14)= 1-P(X

And replacing we got:

P(X>14)= 1- \frac{14-8}{22-8}= 0.5714

The probability that a randomly selected barber needs at least 14 minutes to complete the haircut is 0.5714
