Odds 5:5
Numbers of ways to draw a green marbles: number of ways to draw another marbles.
Explanation:
Consider the provided bag of marble.
The bag contains 5 green marble, 3 blue marbles and 2 red marbles.
The total number of marbles are: 5+3+2=10
The probability of getting a green marble is: 5/10=0.5
That means the probability is 50% that ball will be green.
Drawing green marbles means we want marble should be green and ODDs of drawing a green marble means the marble is not green.
There are 5 green marbles, so there are 5 outcomes that we want (out of 10 outcomes total)
There are 10-5 = 5 outcomes that we don't want a green marble.
Number of outcomes we want is 5
Number of outcomes we don't want is 5
Odds in favor = (wanted outcomes):(unwanted outcomes)
Odds in favor = 5:5
Numbers of ways to draw a green marbles: number of ways to draw another marbles.
