  • Odds are another common way to express a level of
    confidence about an outcome.
  • Very similar to probabilities
  • More common in sports

4
  • In probability theory and statistics the odds in
    favour of an event or a proposition are the
    quantity p / (1 - p), where p is the probability
    of the event or proposition.
  • For example, if you chose a random day of the
    week, then the odds that you would choose a
    Sunday would be 1 to 6.
  • The probability in favour of choosing a Sunday
    would be 1/7.
  • The odds against you choosing Sunday are
  • 6 to1.

Stanley

  • 1. Detroit Red Wings -- 3-1The Red Wings
    rightfully have drawn considerable praise for
    masterful work in making the transition from
    relative free-spending to the cap age, but it
    will take another Stanley Cup to completely
    validate all of that. The only reason the Wings'
    odds aren't shorter is that goalie Dominik Hasek
    will have to prove he can hold up physically
    through the two-month run. For all the Wings'
    strength as a puck-moving, puck-control team
    playing keep-away, does anyone think they can win
    a second time with Chris Osgood in the crease?
  • 2. Anaheim Ducks -- 6-1The defending champs
    face serious roadblocks in the West again -- and
    not just the Red Wings. But with Scott
    Niedermayer and Teemu Selanne back from their
    sabbaticals, and Ryan Getzlaf and Corey Perry
    coming even more into their own, and
    Jean-Sebastien Giguere proven as a money goalie,
    they're big-time threats to repeat unless Chris
    Pronger has too many postseason cases of
    team-hurting brain lock or Todd Bertuzzi's bad
    karma tips the balance.
  • 3. San Jose Sharks -- 8-1The Sharks are the
    hottest team in the league, and the addition of
    Brian Campbell at the deadline added a dimension
    that nudged them to another level. It would help
    if Patrick Marleau, who got going in the second
    half, cranks it up even more in the postseason.
  • 4. Pittsburgh Penguins -- 9-1It might be a case
    of beat 'em this season or maybe forget about it
    for at least a couple of years. The cap era makes
    it tough to even get a dynasty debate started,
    much less maintain a dynasty, and this roster is
    going to be difficult to hold together as it
    matures. But Sidney Crosby, Evgeni Malkin, Sergei
    Gonchar Co. are the favorites to come out of
    the East.

  • 13. Ottawa Senators -- 50-1The defending Eastern
    Conference champions pulled off one of the
    biggest collapses in recent memory, and I suppose
    you could argue that if they awaken and knock off
    the Penguins, that will mean they've snapped out
    of it and their 2007 experience will come into
    play. But Daniel Alfredsson's and Mike Fisher's
    knee injuries are the last straws in a bizarre
    season.
  • 14. Boston Bruins -- 60-1The banged-up Bruins
    did a good job under coach Claude Julien just to
    get here, but it won't last long.
  • 15. Washington Capitals -- 100-1It's a great
    story for the league with Alexander Ovechkin
    taking his refreshing act -- so much talent with
    showmanship that hasn't (yet) gone over the top
    -- into the postseason, but it won't last long.
  • 16. Nashville Predators -- 150-1Given the
    offseason mess, it's amazing the Predators made
    the playoffs -- and just being competitive
    against the Red Wings would add to the
    accomplishment.
