[FREE SOLUTION] | 91Ó°ÊÓ

91Ó°ÊÓ

Winning all three "Triple Crown" races is considered the greatest feat of a pedigree racehorse. After a successful Kentucky Derby, Corn on the Cob is a heavy favorite at 2 to 1 odds to win the Preakness Stakes. a. If he is a 2 to 1 favorite to win the Belmont Stakes as well, what is his probability of winning the Triple Crown? b. What do his chances for the Preakness Stakes have to be in order for him to be "even money" to earn the Triple Crown?

Short Answer

Expert verified
a. Probability is \(\frac{1}{9}\). b. "Even money" odds require Preakness probability \(\approx 0.707\).

Step by step solution

01

Understanding Odds

Odds of 2 to 1 imply that for every 2 unsuccessful outcomes, there is 1 successful outcome. This translates to a probability of success as \( rac{1}{2+1} = \frac{1}{3}\).
02

Calculating the Probability for Winning the Preakness Stakes

Since Corn on the Cob is a favorite with 2 to 1 odds in the Preakness Stakes, the probability of winning is \(\frac{1}{3}\).
03

Calculating the Probability for Winning the Belmont Stakes

Corn on the Cob has similar odds of 2 to 1 for the Belmont Stakes. So, the probability of winning here is also \(\frac{1}{3}\).
04

Finding Probability of Winning the Triple Crown

In order to win the Triple Crown, Corn on the Cob must win both the Preakness Stakes and the Belmont Stakes. The probability of both events happening is the product of their individual probabilities: \(\frac{1}{3} \times \frac{1}{3} = \frac{1}{9}\).
05

Understanding "Even Money" Odds

"Even money" means a 1 to 1 chance, translating to a probability of \(\frac{1}{2}\). This means having equal chances of winning or losing.
06

Determining Preakness Odds for Even Money Triple Crown

Let the probability of winning each race be \(p\) such that the combined probability for both winning the Preakness and Belmont Stakes should be \(\frac{1}{2}\). Therefore, \(p \times p = \frac{1}{2}\), leading to \(p = \sqrt{\frac{1}{2}} = \frac{1}{\sqrt{2}}\). However, to simplify, \(\frac{1}{\sqrt{2}}\) is roughly \(0.707\). For simpler odds, this probability suggests his odds need to be closer to 1 to 0.414 (approximately).

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Odds in Statistics
Odds are a common way of expressing the likelihood of an event. Unlike probabilities, which are ratios of successful outcomes to all possible outcomes, odds represent the likelihood of success relative to failure. For example, when the odds are expressed as 2 to 1, it implies that for every 2 unsuccessful outcomes, there is 1 successful outcome. This ratio shows the relationship between losing and winning possibilities.
To convert odds to probability, you sum the two numbers in the odds ratio (2 + 1 = 3) and then divide the number of successful outcomes by this sum. Hence, for odds of 2 to 1, the probability of winning is \( \frac{1}{3} \). Understanding how to convert odds to probability is essential, especially in scenarios where predictions must be made based on statistical data, such as in sports betting or risk assessments.
Triple Crown
The Triple Crown is a prestigious achievement in horse racing, involving three consecutive victories in the Kentucky Derby, Preakness Stakes, and Belmont Stakes. Winning the Triple Crown is highly regarded in the sports world and only a few horses have achieved this. Each race poses unique challenges due to varying distances and conditions, which makes the feat even more extraordinary.
The probability of winning the Triple Crown can be calculated once you have the probabilities of winning each individual race. For instance, if a horse has the same odds of 2 to 1 for the Preakness Stakes and Belmont Stakes, the probability of winning both, and thus achieving the Triple Crown, would be the product of the probabilities of winning each race. This is because the outcomes must occur consecutively, making the overall probability \( \frac{1}{9} \). This intricate calculation underscores the rarity of such a victory in horse racing history.
Sports Statistics
Statistics play an essential role in sports by providing detailed and quantitative measurements of performance and outcomes. In horse racing, statistics help determine the likelihood of a horse winning a race based on past performances, track conditions, and the competition. Odds are a statistical representation of these factors, turning complex data into understandable formats for bettors and sports enthusiasts.
Utilizing statistics effectively in sports involves understanding how variables like a horse's past race speed or jockey's skill level contribute to its chance of winning. This allows bettors to make informed decisions when placing bets, offering a quantitative evaluation of risks versus rewards. Sports statistics is not limited to horse racing; it is a field widely used across all sports to enhance decision-making and improve performance analysis.
Calculating Odds
Calculating odds involves understanding the relationship between different possible outcomes. In general, odds are expressed as a ratio of the number of events that will lead to success to those that lead to failure. To find the probability from odds, sum up the two parts of the ratio and divide the successful outcome by this total.
For instance, odds of 2 to 1 suggest for every three outcomes, only one is successful, resulting in a probability of \( \frac{1}{3} \). Moreover, when it comes to understanding odds like "even money," which means odds of 1 to 1, the probability of success would be \( \frac{1}{2} \).
  • It's imperative to remember that high odds translate to lower probabilities.
  • Low odds indicate higher probabilities of an event occurring.
  • Calculating odds is vital for making probabilistic decisions in uncertain conditions, especially prevalent in sports betting contexts.
Recognizing these concepts allows participants to gauge potential risks and rewards effectively.
