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)?

prob(pink) = 4/14 = 1/7

prob(not pink) = 1 - 1/7 = 6/7

Answer is simple. What chance do you have to draw a pink one? 14 Total erasers, 4 are definitely pink. So, you have a 4/14, or 2/7 chance to draw a pink one. You have a 10/14 or 5/7 chance to draw a NOT Pink eraser.

Okay, If you add 5 + 2 + 4 + 3 you get 14. If you subtract the pink 4 from 14 you get 10.

You turn that into a fraction, 10/14. Which can be simplfied to 5/7!

To find the probability of selecting an eraser that is not pink, we first need to determine the total number of erasers in the jar.

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.
