Answer:

To subtract integers, change the sign on the integer that is to be subtracted. If both signs are positive, the answer will be positive. If both signs are negative, the answer will be negative. If the signs are different subtract the smaller absolute value from the larger absolute value

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
