Exhibit 6-2 The travel time for a college student traveling between her home and her college is uniformly distributed between 40 and 90 minutes. Refer to Exhibit 6-2. The probability that her trip will take longer than 60 minutes is _____.

Respuesta :

Answer: The required probability is 0.6.

Step-by-step explanation:

Since we have given that

It is uniformly distributed between 40 minutes and 90 minutes,

Probability that her trip will take longer than 60 minutes would be

[tex]\dfrac{b-\alpha }{b-a}[/tex]

here, a = 40, b = 90, α = 60

[tex]\dfrac{90-60}{90-40}\\\\=\dfrac{30}{50}\\\\=0.6[/tex]

Hence, the required probability is 0.6.
