1. Introduction to American odds: American odds are one of the three most common types of odds used in sports betting. American odds are represented as a positive or negative number and are used to indicate the potential payout for a bet. If the American odds are positive, the number represents the amount of money you would win if you bet $100. If the American odds are negative, the number represents the amount of money you would need to bet in order to win $100.

2. Understanding positive American odds: If the American odds are positive, this indicates that the bet is an underdog. For example, if the American odds are +200, this means that if you bet $100, you would win $200 if your bet is successful.

3. Understanding negative American odds: If the American odds are negative, this indicates that the bet is a favorite. For example, if the American odds are -200, this means that you would need to bet $200 in order to win $100 if your bet is successful.

4. Introduction to decimal odds: Decimal odds are another common type of odds used in sports betting. Decimal odds represent the potential payout for a bet as a single number. For example, if the decimal odds are 2.00, this means that if you bet $1, you would win $2 if your bet is successful.

5. Introduction to fractional odds: Fractional odds are the final type of odds used in sports betting. Fractional odds represent the potential payout for a bet as a fraction. For example, if the fractional odds are 2/1, this means that if you bet $1, you would win $2 if your bet is successful.

6. Understanding the bet slip: The bet slip is where you place your bets on the DraftKings sportsbook. Once you have selected the odds you want to bet on, you can enter the amount you want to bet and confirm your bet on the bet slip.

7. Placing a bet: To place a bet, simply select the odds you want to bet on and enter the amount you want to bet in the bet slip. Once you have confirmed your bet, it will be placed and you can track the status of your bet on the DraftKings sportsbook.

This is a basic overview of understanding sports betting odds on the DraftKings sportsbook. If you are new to sports betting, it is important to educate yourself on the different types of odds and to understand the bet slip before placing any bets.
