There are two plugs that are in common usage for electric dryers (in the USA): a 3-wire (typically gray, with a "flat" cord) or the 4-wire (typically black, with a round cord). Older installs will probably have the 3-wire, while anything somewhat recent will likely have the 4-wire. They connect to the dryer slightly differently, but there should be a diagram to show how.
This is the same situation with electric ranges, except the plugs are slightly different from the dryer plugs so you can't just use a dryer plug on a range.
