Question

There are 348 identical plastic chips numbered 1 through 348 in a box. What is the probability of reaching into the box and randomly drawing a chip number that is smaller than 213? Express your answer as a simplified fraction or a decimal rounded to four decimal places

Answer 1

We have to find the probability of randomly drawing a chip number that is smaller than 213.

As the chips are numbered from 1 to 348,this probability will be equal to the proportion of chips that have a number that is less than 213.

We have 212 chips in the bag that have a number less than 213, so we can calculate the probability P as:

$P=\frac{X}{N}=\frac{212}{348}=\frac{53}{87}\approx0.6092$

Answer: the probability is 53/87 or approximately 0.6092.
