Answer:
0.3
Step-by-step explanation:
Given: The odds of winning a contest are 3:7
To find: probability of winning the contest
Solution:
Probability refers to chances of occurrence of an event.
Odds are defined as (chances for success) : (chances against success)
Probability of winning = (chances for success) : (chances for success + chances against success)
As odds of winning a contest are 3:7,
(chances for success) : (chances against success) = 3:7
So,
Probability of winning the contest = [tex]\frac{3}{3+7} =\frac{3}{10}=0.3[/tex]
