Respuesta :

rvkacademic

Answer:

12%

Step-by-step explanation:

Odds in favor means number of favorable outcomes : number of unfavorable outcomes

Here favorable outcome is selecting a left-handed person

So odds of 3:22 means that the ratio of selecting  left-handed person to right-handed person is [tex]\frac{3}{22}[/tex]

P(left) = [tex]\frac{3}{3+22} = \frac{3}{25}[/tex]

P(left) as percent = [tex]\frac{3}{25}\cdot100[/tex] = 12%
