There are a total of 30 rubber bands in the box. The probability of picking a pink rubber band is the number of pink rubber bands divided by the total number of rubber bands. So, the probability of picking a pink rubber band is:
10 pink rubber bands / 30 total rubber bands = 1/3 or 0.33 (rounded to two decimal places)
A box contains 10 pink rubber bands and 20 brown rubber bands. What is the probability of picking a pink rubber band?
