prob(pink) = 4/14 = 1/7
prob(not pink) = 1 - 1/7 = 6/7
A jar contains 5 green erasers, 2 striped erasers, 4 pink erasers, and 3 white erasers. You select an eraser at random. What is P(not pink)?
(1 point)
prob(not pink) = 1 - 1/7 = 6/7
You turn that into a fraction, 10/14. Which can be simplfied to 5/7!

The total number of erasers is the sum of the number of green, striped, pink, and white erasers:
Total number of erasers = 5 (green) + 2 (striped) + 4 (pink) + 3 (white) = 14
Next, we need to find the number of erasers that are not pink. This includes the green, striped, and white erasers.
Number of erasers that are not pink = 5 (green) + 2 (striped) + 3 (white) = 10
Now, we can calculate the probability of selecting an eraser that is not pink by dividing the number of erasers that are not pink by the total number of erasers:
P(not pink) = Number of erasers that are not pink / Total number of erasers
P(not pink) = 10 / 14
Simplifying this fraction gives us the probability:
P(not pink) = 5 / 7
Therefore, the probability of selecting an eraser that is not pink is 5/7 or approximately 0.71.
