Answer:
[tex]B\text{ :}\frac{8}{13}[/tex]
Explanation:
Here, we want to get the probability that the horse will win the race
The odds (ratio of two probabilities, the ratio that he will win to that he will not) in favor is 8:5
The probability will thus be the first value divided by the sum of the values
Mathematically, we have this as:
[tex]\frac{8}{8+5}=\text{ }\frac{8}{13}[/tex]
