Question

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

somewhere along the way. Geoff searched from mile 4.5 to mile 7. What is the probability
that he found his phone?

I need help!!

Answer 1

0.3125

Explanation:

Use definition of geometric probability:

`P=\frac{\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=(2.5)/(8)=(25)/(80)=(5)/(16)=0.3125`
