Four quilters are preparing patches for a quilt. When finished, the quilt will contain 200 patches. The quilters’ contributions thus far are in the table below.
Name Number if patches
Find the probability that a randomly chosen patch:
1. Will have been sewn by Elle?
2. Will not have been sewn by Lia?
3. Will have been sewn by Brian or Len?
Add up the number of patches. The compute the fraction done by each... (or not done, if that is what they ask for)
