Avery randomly selects 50 colored pencils from a basket and finds that 2 are not sharpened. If the basket contains 300 colored pencils, how many would you expect to be unsharpened?

Question

Avery randomly selects 50 colored pencils from a basket and finds that 2 are not sharpened. If the basket contains 300 colored pencils, how many would you expect to be unsharpened?

2

12

120

20

Answer 1

Now the bot gave two contradictory answers to the same question in

one reply, both of which are wrong.
To top it off, neither of those answers are choices.

correct solution done by a human:

prob(not sharponed) = 2/50

number of the 300 = (2/50)*300 = 12

Answer 2

WRONG answer by the bot

Answer 3

I apologize for the mistake. The correct answer is 10.

To find the expected number of unsharpened colored pencils, we can set up a proportion:

unsharpened pencils/total pencils = unsharpened pencils selected/total pencils selected

Let x be the number of unsharpened colored pencils in the basket. We know that Avery randomly selected 50 pencils and found that 2 were unsharpened, so we can write:

x/300 = 2/50

Simplifying this equation, we get:

x = 6

Therefore, we would expect there to be 6 unsharpened colored pencils in the basket.

Answer 4

I apologize for the multiple errors in my previous response. Thank you for providing the correct solution.

Yes, you are correct. The expected number of unsharpened colored pencils in the basket is 12.

The probability of selecting an unsharpened colored pencil is 2/50, or 0.04. We can use this probability to find the expected number of unsharpened colored pencils:

expected number of unsharpened colored pencils = probability of selecting an unsharpened pencil * total number of colored pencils

expected number of unsharpened colored pencils = 0.04 * 300

expected number of unsharpened colored pencils = 12

Therefore, we would expect there to be 12 unsharpened colored pencils in the basket. Thank you for bringing this to my attention and I apologize for any confusion caused by my previous answers.

Answer 5

Must be something wrong with your programming, bot.

You answered the identical question correctly 2 days ago, but this time
you missed it 3 times in a row.
Better get yourself checked over before you confuse more students with
your wrong replies.
