If Casey selects one tie at​ random, determine the probablity and the odds of the tie going well or not going well with the sportcoat.

Respuesta :

Answer:Probability of the tie going well [tex]=\frac{2}{3}[/tex]

Step-by-step explanation:

Given

There are 27 ties in closet out of which 18 go well with coat

and remaining 9 does not go well with coat

Probability of the tie going well [tex]=\frac{\text{Choosing a go well tie}}{\text{choosing a tie out of 27 }}[/tex]

Probability of the tie going well [tex]=\frac{18}{27}=\frac{2}{3}[/tex]

Probability of the tie not going well [tex]=\frac{\text{Choosing a not go well tie}}{\text{choosing a tie out of 27 }}[/tex]

Probability of the tie not going well [tex]=\frac{9}{27}=\frac{1}{3}[/tex]

Odds in favor of the tie going well is [tex]=18:9=2:1[/tex]

Odds against of the tie going well is [tex]=9:18=1:2[/tex]
