A sporting goods store received an order of 80 baseball caps, of which 12 are green. If 1 of the 80 caps is selected at random, what is the probability it will not be green.
There are 80 caps in total and 12 of them are green, so there are 80 - 12 = 68 caps that are not green.
The probability of selecting a non-green cap is therefore 68/80.
Simplifying this fraction, we get:
68/80 = 17/20
Therefore, the probability of selecting a cap that is not green is 17/20, or approximately 0.85.
To find the probability that a cap is not green, we need to determine the number of caps that are not green and divide it by the total number of caps.
The number of caps that are not green can be calculated by subtracting the number of green caps from the total number of caps:
Number of caps that are not green = Total number of caps - Number of green caps.
Let's calculate that now:
Number of caps that are not green = 80 - 12 = 68.
Therefore, there are 68 caps that are not green.
Now, we can calculate the probability that a randomly selected cap will not be green by dividing the number of caps that are not green by the total number of caps:
Probability of selecting a cap that is not green = Number of caps that are not green / Total number of caps.
Let's calculate that now:
Probability of selecting a cap that is not green = 68 / 80.
Therefore, the probability of selecting a cap that is not green is 68/80 or 0.85, which can also be expressed as 85%.
