LAS VEGAS (AP) _ Oddsmakers have installed Texas cowboy Colby Donaldson as the favorite to win the $1 million grand prize on the CBS reality-based series ``Survivor.''

Donaldson is the 3-2 favorite at the Stardust hotel-casino and the 2-1 favorite at the Bally's and Paris hotel-casinos.

``Colby has won many immunities and he looks like the strongest,'' said Joe Lupo, manager at the Strip resort's race and sports book.

Tina Wesson is Lupo's second favorite at 2-1, while Keith Famie is at 3-1 followed by Elisabeth Filarski at 5-1.

The odds are only hypothetical because state law prohibits wagers on events in which the outcome already is known, and CBS, unlike the oddsmakers, knows how this contest ends. The winning survivor will be revealed in a two-hour finale May 3.

John Avello, director of the race and sports books for Bally's and Paris hotel-casinos also favors Donaldson but likes footwear designer Filarski as his second favorite at 5-2. Famie is next at 7-2, followed by Wesson at 4-1.
