i do not know how to do this question. can someone help me with this question?
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)?
how many of the erasers are not pink?
How many total erasers are there?
P(~pink) = #~pink/#total
There are 4 pink erasers and 14 in total so is the answer 4/10 or 2/5?
NO. The answer is 10/14 since there are 10 not-pink erasers out of 14 total.
the guys right 25 is the answer i got 100%
@john what were the answers
JUST PUT ALL THE ANSWERS
Of course! I can help you with that. To find the probability of not selecting a pink eraser, we first need to determine the total number of erasers in the jar.
In this case, the jar contains:
- 5 green erasers
- 2 striped erasers
- 4 pink erasers
- 3 white erasers
To find the total number of erasers, we sum up these quantities:
5 + 2 + 4 + 3 = 14
So, there are 14 erasers in total.
Next, we need to determine the number of erasers that are not pink. In this case, it includes the green, striped, and white erasers.
So, the number of erasers that are not pink is:
5 (green erasers) + 2 (striped erasers) + 3 (white erasers) = 10
Therefore, the number of erasers that are not pink is 10.
Finally, to find the probability of not selecting a pink eraser, we divide the number of erasers that are not pink (10) by the total number of erasers (14):
P(not pink) = 10/14 = 5/7
So, the probability of not selecting a pink eraser is 5/7.
