The waiting time for a bus at a certain bus stop has a uniform distribution over the interval from 0 to 25 minutes. (a) What is
trapecia [35]

Answer:

(a) The probability that a person has to wait less than 6 minutes for the bus is 0.24.

(b) The probability that a person has to wait between 10 and 20 minutes for the bus is 0.40.

Step-by-step explanation:

Let The random variable <em>X</em> be defined as the waiting time for a bus at a certain bus stop.

The random variable <em>X</em> follows a continuous Uniform distribution with parameters <em>a</em> = 0 and <em>b</em> = 25.

The probability density function of <em>X</em> is:

f_{X}(x)=\left \{ {{\frac{1}{b-a};\ a

(a)

Compute the probability that a person has to wait less than 6 minutes for the bus as follows:

P(X

                =\frac{1}{25}\times \int\limits^{6}_{0}{1}\, dx

                =\frac{1}{25}\times [x]^{6}_{0}

                =\frac{1}{25}\times [6-0]

                =0.24

Thus, the probability that a person has to wait less than 6 minutes for the bus is 0.24.

(b)

Compute the probability that a person has to wait between 10 and 20 minutes for the bus as follows:

P10

                          =\frac{1}{25}\times \int\limits^{20}_{10}{1}\, dx

                          =\frac{1}{25}\times [x]^{20}_{10}

                          =\frac{1}{25}\times [20-10]

                          =0.40

Thus, the probability that a person has to wait between 10 and 20 minutes for the bus is 0.40.
