Answer:
17.65% probability a rider must wait between 1 minute and 1.5 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 between c and d is given by the following formula
[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]
For this problem, we have that:
[tex]a = 30, b = 200, c = 1*60 = 60, d = 1.5*60 = 90[/tex]
[tex]P(60 \leq X \leq 90) = \frac{90 - 60}{200 - 30} = 0.1765[/tex]
17.65% probability a rider must wait between 1 minute and 1.5 minutes
