On each of the first three days of January, there is a 1/3 chance that it will snow where Bob lives. On each of the next four days, there is a 1/4  chance that it will snow. What is the probability that it snows at least once during the first week of January?

I got 283/6912, or 4235/6912 I don't know if these are right??? Please help asap! Thank you in advance! This is Complementary counting
