Question

1. Geoff rode his bike along an 8-mile path and lost his cell phone at some random location

Answer 1

Answer:

0.3125

Step-by-step explanation:

Use definition of geometric probability:

$P=\dfrac{\text{Desired Length}}{\text{Total Length}}$

In your case,

Total Length = 8 miles

Desired Length = 7 - 4.5 = 2.5 miles,

so the probability is

$P=\dfrac{2.5}{8}=\dfrac{25}{80}=\dfrac{5}{16}=0.3125$
