Plastic drinking straws are manufactured to fit into drinks cartons which have a hole in the top. A straw fits into the hole if the diameter of the straw is less than 3 mm. The diameters of the straws have a normal distribution with mean 2.6 mm and standard deviation 0.25 mm.

Question

- 500 straws are chosen at random. Use a suitable approximation to find the probability that at least 480 straws fit into the holes in drinks cartons.

Look at the time stamp on each post. That is Eastern time in the US (including New York City). If you post in the middle of the night here, it'll likely be hours and hours before anyone answers since most of our math tutors are in Eastern or Central time zones in the western hemisphere.

That's why this is among the directions on the Post a New Question page:
Please be patient. All tutors are volunteers, and sometimes a tutor is not immediately available. Please be patient while waiting for a response to your question.
