3ware to 4 wire dryer wall plug

I need to wire in a 4 wire wire plug in at the wall for my new dryer but the wire I want to splice into is only 3 wire (black /white/Ground) is this possible ?

No, and the black/white/ground cable was never really legal for a dryer although widely used. As a retrofit installation you could leave the three prong receptacle (should be a NEMA 10-30) and replace the cord on the dryer to match. When replacing the cord, you would need to make sure the bonding strap or wire from the neutral terminal is securely attached to the metal frame. If the dryer is currently wired for a four prong cord, the bond should be unattached.

I'd suggest doing it right and replacing the 10-2 cable with 10-3 NM-B cable which comes with the 4th wire, the bare ground. Using 10-2 NM cable (aka romex) for a dryer circuit isn't safe and has never been allowed by code.
