Answer:

Step-by-step explanation:
Add all paper clip sizes together:

They want the probability of either a small or medium being chosen, so you add both paper clips sizes together.

Now put the number of small and medium paper clips together over the total number of paper clips to find the probability.
Can divide 350 and 500 by 50, which simplifies it down to 7/10.

Make them both improper fractions
13/3 divided by 11/9
Divide = multiply reciprocal
13/3 * 9/11 = 117/11 = 10 7/11
