Metro buses are scheduled to arrive at each stop every 30 minutes. If the time a person waits at a bus stop is uniformly distributed and the maximum possible wait time for a bus is 30 minutes, what is the probability that you will wait more than 25 minutes for a bus

Respuesta :

Answer:

The probability is [tex]P(X > 25 ) = 1.667[/tex]

Step-by-step explanation:

From the question we are told that

    The  maximum wait is  [tex]b = 30 \ minutes[/tex]

      The  minimum wait would be  [tex]a = 0\ minutes[/tex]

Generally the probability that you will wait more than 25 minutes for a bus is mathematically represented as

   [tex]P(X > 25 )[/tex]

Now given that the time a person waits is uniformly distributed and that the maximum is  30 then we can evaluate the above probability as

    [tex]P(X > 25 ) = P(25 < X < 30 ) = \frac{30 - 25}{30 - 0}[/tex]

     [tex]P(X > 25 ) = 1.667[/tex]
