How to travel between Las Vegas and Death Valley by public transportation?

Learning that February is a good time to visit the Death Valley, I decided to pay a visit there with a bunch of friends from LA. The friends are driving from LA to the Death Valley, and I am traveling to the Death Valley from Las Vegas -- yes, we are meeting up at the Death Valley.
I can't drive. Since inside the Death Valley, we prefer to travel ourselves, I cannot join any organized tour from Vegas to the Death Valley. So I have to take public transportation from Vegas to the Valley and back.
Is it even possible? If so, how should I do this?
Thanks @Greg for citing the information that no public transportation from Vegas to the Valley is available. The least thing I want to do is to ask my friends to drive to Vegas to pick me up. That is a huge detour. So I did some math.
The figure shows the route from LA to the Valley. What if I go towards LA direction along 15 and wait for them to pass by and pick me up in the car? This turning point is a town called Baker, CA. I checked Greyhound from Las Vegas to Baker, CA. There is none either. Any solution to this situation so far?
