A company produces 3000 memory cards each day. Every day 25 a randomly selected for testing. One day, one of those test failed. About how many of the memory cards produce that day are likely to fail?

Question

60
429
25
120

Answer 1

To estimate how many of the memory cards produced that day are likely to fail, we can set up a proportion using the ratio of cards tested and the cards that failed.

The ratio of cards tested = 25 / 3000 = 1 / 120

Since one card failed the test, we can estimate that approximately 1/120 of the memory cards produced that day are likely to fail.

Therefore, about 120 of the memory cards produced that day are likely to fail.

So the answer is 120.
