To find the odds of grabbing a green soda can, we first need to determine the total number of cans and the number of green cans.
There are:
- 30 red cans
- 20 green cans
The total number of cans = 30 + 20 = 50.
The odds of an event happening is expressed as the ratio of the number of successful outcomes to the number of unsuccessful outcomes.
In this case:
- Successful outcomes (grabbing a green can) = 20 (the number of green cans)
- Unsuccessful outcomes (grabbing a red can) = 30 (the number of red cans)
So, the odds of grabbing a green can are: \[ \text{Odds (green)} = \frac{\text{Number of green cans}}{\text{Number of red cans}} = \frac{20}{30} = \frac{2}{3} \]
Therefore, the odds of reaching in and grabbing a green can are 2:3.
