Answer:
The probability of randomly drawing a chip number smaller than 219 from a box with 338 identical plastic chips is approximately 0.6444.
Step-by-step explanation:
To find the probability of randomly drawing a chip number smaller than 219, we need to determine the total number of chips and the number of chips that are smaller than 219.
Given that there are 338 chips numbered 1 through 338, the number of chips smaller than 219 is 218 (since the chips are numbered from 1).
The probability can be calculated by dividing the number of chips smaller than 219 by the total number of chips:
Probability = (Number of chips smaller than 219) / (Total number of chips) = 218 / 338 = 0.6444 (rounded to four decimal places).
