Question 205416: Can you please help me answer this?
Among 170 households surveyed, 41 have a video camera, 58 have a snapshot camera, 36 have binoculars, 9 have a video camera and a snapshot camera, 6 have a snapshot camera and binoculars, and 3 have all three products. What is the probability that a household will have a snapshot camera or binoculars? Express the answer as a fraction.
I drew a venn diagram with three circles. "v" for video cam, "s" for snapshot and "b" for binoculars. I put three in the very middle and found that 3 houses have "s" and "b", and 6 have "v" and "s." I don't know how to find how many have "v" and "b" so without that information I can't figure out how many have a snapshot camera or binoculars.

You can put this solution on YOUR website! I don't know how to find how many have "v" and "b" so without that information I can't figure out how many have a snapshot camera or binoculars.
