The scheduled commuting time on the MTA Marc train from BWI to DC is 65 minutes. Suppose that the actual commuting time is uniformly distributed between 64 and 74 minutes. What is the probability that the commuting time will be less than 70 minutes

Answer:

60% probability that the commuting time will be less than 70 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

[tex]P(X < x) = \frac{x - a}{b-a}[/tex]

Suppose that the actual commuting time is uniformly distributed between 64 and 74 minutes.

This means that [tex]a = 64, b = 74[/tex]

What is the probability that the commuting time will be less than 70 minutes

[tex]P(X < 70) = \frac{70 - 64}{74 - 64} = 0.6[/tex]

60% probability that the commuting time will be less than 70 minutes
