Let
L=event that a selected worker has low risk
H=event that a selected worker has high risk
We need to find
P(HL)+P(LH)
=5*20/(25*24)+20*5/(25*24)
=1/6+1/6
=1/3
The answer is y = 8 from the photo

To solve this we are going to use the free distance fallen formula:

where

is the distance

is the gravity of Earth


is the time in seconds
We know from our problem that the
