To understand the probabilities and odds for a sports event, let's break down the given odds for the match between USA and Uruguay in the Copa America. The odds provided are:
- Team 1 (USA) to win: 2.55
- Draw (X): 3.20
- Team 2 (Uruguay) to win: 2.90
### Converting Odds to Probabilities
Odds can be converted to implied probabilities using the formula:
\[ \text{Probability} = \frac{1}{\text{Odds}} \]
#### 1. Probability of USA Winning
\[ \text{Probability of USA Winning} = \frac{1}{2.55} \approx 0.3922 \]
\[ \text{Probability (Percentage)} = 0.3922 \times 100 \approx 39.22\% \]
#### 2. Probability of Draw
\[ \text{Probability of Draw} = \frac{1}{3.20} \approx 0.3125 \]
\[ \text{Probability (Percentage)} = 0.3125 \times 100 \approx 31.25\% \]
#### 3. Probability of Uruguay Winning
\[ \text{Probability of Uruguay Winning} = \frac{1}{2.90} \approx 0.3448 \]
\[ \text{Probability (Percentage)} = 0.3448 \times 100 \approx 34.48\% \]
### Verifying the Sum of Probabilities
The sum of the probabilities should ideally be 100%, but due to rounding and the bookmaker's margin, it may slightly exceed 100%.
\[ 39.22\% + 31.25\% + 34.48\% \approx 104.95\% \]
This total is above 100%, indicating the bookmaker's margin or "overround."
### Converting Probabilities to Odds
If you want to convert probabilities back to odds, you can use the formula:
\[ \text{Odds} = \frac{1}{\text{Probability}} \]
For example, if you have a probability of 39.22%, the corresponding odds are:
\[ \text{Odds} = \frac{1}{0.3922} \approx 2.55 \]
### Summary
- USA to win: 39.22% probability, odds of 2.55
- Draw: 31.25% probability, odds of 3.20
- Uruguay to win: 34.48% probability, odds of 2.90
These probabilities help to understand how likely each outcome is according to the bookmaker's odds.
